Firefox Community Forum

I have installed the LastPass extension for Firefox, more than once, but the LastPass icon does not appear in my browser bar. It used to be there, but disappeared a few weeks ago. I have tried to reinstall the extension, but it has had no effect.

I am having issues signing in to the playstation store using firefox. It works on edge (although I have the same issue in ungoogled chromium). I have tried refreshing but that didn't work. I uninstalled it and deleted all mozilla folders in appdata, then tried again without signing in to my mozilla account on a fresh install but i'm still having the issue. It might be a windows configuration issue because I don't see why this would work on edge but not on firefox. I've tried disabling all cookie and tracking protection features but I still have the same issue.

My Firefox Updated today and just closed randomly, on reopen it was brand new with no history/bookmark etc. I didn't have a firefox account at the time. Is there a way to restore it since i used a lot of mozilla auto set passwords which have also been deleted.

Since the last update (was executed today in my case 16-07-2024), firefox has been very slow and freezing and crashing. Also, somehow it is the only browser that can't handle yahoo finance new charts and keeps freezing....so many issues in a short span of time, please check. I have tried other browsers and things seem to work fine there, so, it is not my computer or OS.

I want to know what should I change to change between these two appearances. I tried to change everything with `browser.search` in about:config, but I don't see anything that changed it.

Hi! Why I lost the customize button on my Firefox's home page? This happened after the last Firefox upgrade.

Your help will be greatly appreciated.

ATT is my internet service provider. I use their website as my home screen. Yesterday, I started getting an error message when I tried to go on-line. I have contacted ATT, and they have determined that the problem is with Firefox, and not their website. I can go from the ATT screen to any other website, and it works fine. This is the message that I get:
