I know there are things to gripe about, and things that don't work to one's liking and so on, but... I would like to thank the team behind Firefox for the work they put in. Firefox is a damned good piece of software and I really appreciate it - thank you for it.
Recent-ish developments I particularly like:
* 'Reader mode' - thank god for this. The internet is insufferable without adblockers and this only makes it even more bearable
* Embedded PDF reading/editing - still a bit flaky, but thank you for reducing further the need to have any Adobe product on my machine. Right now I only keep Acrobat around for the dreaded 'signatures'.
