**Feedback Suggestion for Mozilla Thunderbird:** Mozilla Thunderbird currently lacks a direct **email blocking (blacklist) feature** for specific addresses or domains. Users must manually create message filters to delete or junk messages from unwanted senders, which is less intuitive and efficient. **Suggested Improvements:** 1. **Implement a Dedicated Block List:** Add a user-friendly "Block Sender" option (e.g., via right-click on a message) that automatically adds the sender's address to a centralized blacklist. Emails from blacklisted addresses should be automatically deleted or moved to Junk/Trash upon arrival. 2. **Automate Blacklist Population from Filters:** Enhance the message filter system by allowing filters to automatically add matching addresses to the block list. For example: * If a message is **manually marked as Junk**, provide an option to "Add sender to Block List." * Allow filters to include an action like "Add sender to Block List" when conditions are met (e.g., email is tagged with `JUNK` or `SPAM`, or has a high spam score). This would streamline spam management, reduce manual filter creation, and bring Thunderbird's functionality in line with other modern email clients.   ... View more

I like to organize my tabs into groups. Usually, I research an idea outside of a tab group (opening tabs to the far right of the tab bar) before right clicking the tabs I've opened and adding them to their appropriate tab group. This is to clean up my tab bar. When the tabs go the the group, though, it unfolds the tab group. I just want to stash away those tabs and not use the group anymore. Thus, I have to click the tab group rectangle so that it refolds. Please add an option in about:config or in the settings menu that toggles whether this unfolding behavior happens. Go firefox! ...

The default behavior in Firefox when closing a tab is that it would simply go to the next tab. This is often fine, but in cases where the next tab is muted, it would go to it and unmute it. This is problematic because the user might have a tab muted intentionally for a reason. Having this behavior means the tab would unmute/load without the user's explicit consent. I think there should be small changes to this behavior. Maybe something like this: 1. If next tab is loaded (not muted), go to it, upon closing current tab. 2. If the next tab is muted/unloaded, check the previous tab, if it's loaded, go to it. 3. If not, go to the closest loaded tab, in whichever direction, (or maybe go to the previously focused tab?). I haven't thought this through, and I'm sure Firefox developers can come up with a much smarter behavior than this, but this is just an example to clarify my idea further. Another vertical tab add-on does the latter, it simply goes to the previously focused tab regardless of direction or position. This has its drawbacks of course, so there's no perfect approach here. But anything is better than loading a muted tab. Thank you. ... View more

Firefox’s current customization options for toolbars and the vertical tab sidebar are fragmented. Users must navigate separate menus (gear icon) to customize the sidebar , and there’s no intuitive way to move icons or tabs between from the (vertical) side bar to the main horizontal toolbar . This limits flexibility and creates a disjointed experience for users who want a seamless, personalized browser layout. Ideally I can decide which icons show up in the sidebar, which show up in the main address bar or toolbar. And all of this should be accessible in the drag and drop Customize Toolbar... page  ...

  Dear Mozilla Team, I tried the new firefox webapp function. Cool function! I’m using Firefox’s Web App feature to create shortcuts for a web application that uses a base URL (e.g., https://app.example.com/) and customer-specific paths (e.g., https://app.example.com/customer123). Currently, Firefox only saves the base URL when creating a Web App, which renders the shortcut non-functional for our use case, as the base URL alone does not provide access to the specific customer environment. Other browsers, like Microsoft Edge, allow saving the full URL (including the path) when creating a Web App shortcut. This functionality is crucial for our workflow, as each customer requires a unique path extension. Request: Could you please enhance the Web App feature in Firefox Desktop to save and use the full URL (including the path) when creating a Web App? This would align Firefox with other browsers and significantly improve usability for applications relying on path-based routing. Thank you for considering this improvement. I’m happy to provide further details if needed. KR ... View more

I personally find the translation option offered in firefox very useful: no need to switch tab, or to use an LLM for a simple translation, and still the provided result is generally context-accurate. [I mostly use the pop-up feature instead of the whole page translation, both because i find the translations imperfect, and to further improve my language skills]  One feature i find annoying however is the seemingly incapability of the translator pop-up window to effectively recognize the selected language when it consists of very short-context (think one or two words). It always reverts back to English by default, and it can get tedious to specify 10 times in a row that the language in question is not english Hence my proposal: - allow for more flexibility in the use of the translator by enabling the user to specify in the translation setting which should be the default source language, and which should be the default output language. ...

Thunderbird for desktop should also support tags without a color (ie transparent). You can apply multiple tags to a message, and then the message on the list is displayed in the color of the first tag alphabetically. Eg if you tag a message as 'Later' (say, yellow) and 'Travel' (say, orange), the message will appear in yellow, but you may want 'Travel' to be the dominant tag. Currently, I would rename 'Later' as 'zLater' to make sure it is listed last and deprioritised, but it gets more complicated when you want to apply several tags to a message.  A transparent 'Later' could be applied without affecting the display color, but 'Later' could still be used in filtering rules etc.              ...

Hello Mozilla Team, One of the primary reasons I use Firefox on Android is its unique support for browser extensions, which is a key advantage over Chrome. However, one of the most in-demand extensions, the DeepL Translator, is currently unavailable for Firefox on Android. As a DeepL Pro subscriber, I (and many others) rely on its full-page translation feature, which we cannot use on mobile. The DeepL extension already exists for desktop Firefox. The technology in Firefox for Android is perfectly capable of running it, but it seems DeepL has not officially "enabled" it for the mobile list. Could the Mozilla team reach out to DeepL (a major player in the translation space) and encourage them to list their add-on for Firefox on Android? Adding high-profile, in-demand extensions like DeepL to the official Android list would be a significant competitive advantage for Firefox and would solidify its position as the best browser for power-users on Android. Thank you. ... View more

When setting multiple URLs as a home page so that they open when the browser is started, it would be nice if there were syntax that took advantage of the tab grouping feature and could be used to indicate if tabs should be grouped together. ... View more

It doesn't feel right when I resize the Thunderbird's window, almost everything and more obvioulsy the messages list pane will be resized in a way that is totally counter-intuitive. It almost always needs to be adjusted. I think, either the proportion of the resizing of all pane should be look for better reactions; or, only the message's content view pane should be resized and the rest stay untouched. It always react differently, that's odd! ... View more

The new Google Lens feature in Firefox is nice and something people have wanted for a while. But it only works when there’s already an image on the page. That’s pretty limited. It would be much better if we could use it anywhere on a webpage — like take a quick screenshot or select part of the screen and search that on Google Lens. There’s already an extension that does this called “To Google Lens” (link). It lets you right-click, drag to capture an area, and send it straight to Lens. If Firefox added that same ability natively, it’d make the feature complete. You wouldn’t need extra extensions, and it would feel way smoother and more useful in everyday browsing. ... View more

This is mainly a feature request for those who have the misfortune to bank online with santander/cahoot in the uk.  Both of these banks will occasionally attempt to overwrite a password stored in the password manager with "disable-pwd-mgr-2" or similar.  Thankfully, the password manager is intelligent enough to not blindly replace the password with this junk but the repeated appearance of the prompt is rather vexatious.  By allowing users to specify a list of "passwords" that Firefox should never prompt to save, this would be defeated.   I understand that this is a hyper-specific use case and thus this would be very low priority (and may never be implemented, given that someone would have to maintain it after its implemented) but it would be greatly appreciated!   Although I could choose to never save passwords on a per-site basis, this would be irritating if I was ever to change the password. ...

After using Quick filter and "display in list" the folder pane is not visible anymore. Maybe someone wants to move the filtered e-mails into a folder by dragging the e-mails to that folder. Before commenting: - I am aware of the "rightclick -> move"-function but it is not intuitive; - I get no results if I just use the quick filter alone and it displays "press enter to look further", no mather with buttons I press (and another tip of mine was to make it visible on the buttons if you have pressed "contact" or not. ...

Dear Thunderbird Team, I hope this message finds you well. I wanted to share a suggestion that could improve the usability of Thunderbird’s calendar feature. It would be extremely helpful to have an option to filter and display only the appointments that have been shared with me — not all calendar entries. This would make it much easier to focus on relevant shared events, especially when managing multiple calendars or working in collaborative environments. You can also identify my account easily, as my email address is already associated with the shared events in question. Thank you for your continued work on Thunderbird — it’s a fantastic tool that I use daily. Kind regards, Dr. Farbod Aprin ... View more

Hi! It would be great that the toolbar of the PDF viewer in Firefox were customisable. I would like to be able to decide which features (and their icons) were visible on the bar and which others were collapsed. Currently, it is imposible to change the distribution of the tools on the bar... or I do not know how to do it. Thank you very much. ... View more

Currently, Firefox Translate automatically detects and translates pages using on-device models. However, users have no way to correct translations that feel unnatural or inaccurate for their local language. I propose adding a “Custom Translation Dictionary” feature that works like the spellcheck dictionary in Microsoft Word: When users see a translated phrase that feels wrong or awkward, they could right-click it and choose: → “Add custom translation…” Firefox would then store the corrected translation locally in a file (for example, translate_user.json). During future translations, Firefox checks the user’s local dictionary first. If a matching phrase exists, it uses the user’s preferred translation instead of the built-in one. Optionally, users could export or submit their dictionary to Mozilla, helping improve community translations. Why this matters: Many expressions, idioms, and slang terms vary by region and culture. Allowing users to store and refine their own translations makes Firefox Translate more natural and adaptable. This feature empowers communities to crowdsource better translations without relying on external AI services. It also aligns with Firefox’s focus on privacy — everything is processed locally unless the user explicitly chooses to share their data. Example use case: Default translation: “Reload” → “Muat ulang” User prefers: “Segarkan” Firefox remembers this correction for future translations. Over time, these personalized dictionaries could grow into valuable language resources that Mozilla can integrate into future translation models. Optional extra: Add a small “Suggest better translation” button next to translated text. This could either store the suggestion locally or submit it (with user consent) to Mozilla’s localization platform (Pontoon). Conclusion: This feature would make Firefox Translate more flexible, more community-driven, and more aligned with real-world language use. It also opens the door for users to teach Firefox their language — just like adding words to a spellchecker. ... View more

I would love Firefox to include an option that automatically hides the entire top part of the browser — including the tab bar, address bar, and buttons — and only shows it again when the mouse hovers over the upper edge of the window. This would allow users to enjoy a clean, distraction-free experience, similar to fullscreen mode but without hiding the operating system’s taskbar or requiring F11. The idea is simple: When the user activates “Minimal Mode,” the top UI area hides automatically. When moving the mouse to the top edge, the bars reappear smoothly. When the mouse leaves, they auto-hide again. This would be especially useful for laptops and small screens, giving more space to web content while keeping the browser controls accessible when needed. Thank you for considering this idea — Firefox already offers great customization, and this feature would take minimalism and usability to the next level. ... View more
