Firefox tabs sometimes feel a bit slower than usual

henery — Fri, 17 Oct 2025 20:02:33 GMT

Hi everyone,
Lately I’ve noticed some tabs in Firefox take a bit longer to load than before. Nothing major, just curious if anyone else has seen this too?
Maybe a recent update or setting change?

Hey Henery, yeah, I’ve noticed that too lately. It seems like some of the recent Firefox updates have slightly changed how background tabs and memory caching work, so pages can feel a bit slower to load at times, especially if you’ve got a lot of tabs open. Clearing the cache or disabling unused extensions sometimes helps a bit. It’s nothing major, probably just Firefox adjusting after a recent update, but you’re definitely not the only one seeing it.

Yes, I have a website as well. I’ve been working on it recently and focusing on making it simple and useful for people who want to experiment with different text styles. You can check it out here: Police d'écriture. I’d also be interested to hear what you think about it.

I’ve run into this kind of slowdown before, and in my case it wasn’t really the number of tabs by itself. Extensions and pages that keep running in the background seemed to make the delay more noticeable.

One thing worth trying is Firefox’s Troubleshoot Mode for a while. If the tabs feel normal there, that’s a good indication that an extension or customization is contributing to the slowdown. From there, disabling extensions one at a time is a much easier way to find the culprit than clearing everything and hoping it fixes the issue.

I also found this Firefox performance troubleshooting guide useful because it goes through the common causes and the checks you can make before resetting the browser and you can check it out here: Şekilli Nick

I like how straightforward this calculator is. Being able to adjust hours and weeks worked makes the hourly estimate much more realistic than simply dividing a salary by 2,080. The pay-period breakdown Salary to Hourly Calculator is also useful when comparing job offers or planning a budget.

I really like how simple this tool is. Being able to type something once and instantly compare different cursive, script, gothic, and italic styles is genuinely useful, especially for social media bios, usernames, and creative designs. The copy-and-paste feature also makes Cursive Font Generator it much more convenient than installing a separate font.

sign-scribe I’ve noticed something similar when I have quite a few tabs open. Clearing the cache and checking which extensions are running seems to help, especially after Firefox updates.

I also spend a lot of time testing browser-based tools such as my signature generator, so smooth tab loading makes a noticeable difference when switching between different pages and testing features. Hopefully Firefox continues improving tab and memory performance.

I am experiencing exactly same.

I’ve noticed similar performance differences when switching between multiple tabs, especially when using several browser-based tools at the same time. I’ve been working on a lightweight Arabic Hijri/Gregorian calendar website, and keeping the pages fast and simple has been an important part of the design.

It includes Hijri/Gregorian date conversion, age calculation, date differences, and Islamic event dates. If anyone is interested in checking it out, here it is:

I’d also be interested to hear whether it loads quickly for you in Firefox, especially when several tabs are open.
