Same here... I read comments all the time in browser threads about these issues in Firefox and I must be lucky or my basic install with just uBO is the difference (I also don't use any Google websites outside of search and Youtube). I have been daily FF user on both desktop and laptop for 4+ hours a day since I left Opera when it changed to a Chromium base and I can probably count on one hand the issues I've had with FF working with sites properly. One was a repeatable memory leak that would crash FF like 4 years ago that I submitted as a bug report and it was fixed in next release.

To me FF is just as fast in general browsing than anything else. I routinely try other browsers and I just feel "wrong" using any of the Chromium based others of Edge/Brave/Vivaldi when FF needs us right now. It needs the us to stand against non-open source web browsers and as an alternative engine to the web. I really like Vivaldi and would be my 2nd choice (then Edge then Brave, refuse to use Chrome) but it isn't open-source nor does it do anything to protect privacy.

If FF is giving crashes, issues at sites etc please try at least refreshing your install in the options and don't install so many extensions. Even better backup your bookmarks and uninstall it while making sure to also delete all users\$username\Appdata folders as well then reinstall.

ah, good point about the extensions, I do have uBlock Origin and NoScript, so it could actually be those, even if the latter is basically off 90% of the time... thank you for pointing that out ^_^

I similarly have had very few issues with firefox and use it every day.

I fall back to edge if I have an issue but it's not common.

It's more a function of the websites you visit. When your bank or pay is locked behind a site that breaks on firefox... it's hard to keep the faith.
