Firefox Community Forum

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

I Have Had It Installed On Microsoft Edge For About A Year With No Problems. I Had It Installed For About 3 Months On Firefox Then I Needed To Install It Again & I Get The Above Messages. Why Is It Doing This? There Hasn't Been Any Harm Done To My Computer. Also Firefox Needs A Customer Service Phone Number For People To Call & Explain Their Issues It's A Lot Quicker & Easier To Solve Your Problem.

I started getting "can't load XPCOM" errors when starting Firefox. I did a full uninstall, then attempted to install the new version, I still get the same error during the install.

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

I tried installing firefox but microsoft won't let me. an article said to install from firefox website so I tried. How do I install direct from firefox website because still goes to microsoft and won't install. I want firefox browser and microsoft so I can do email and internet at same time. besides all microsoft does when searching internet is stick me with bing. I don't like bing. firefox does better more concrete searching not all over the place. How can I install from firefox website and it does not go to microsoft.

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

Since the latest update Firefox doesn't show up in the browser list. I don't want to uninstall to reinstall because I have too many settings in my browser that I don't wish to reset. Please solve the problem.

Hi, I‘m not sure if I selected the right topic for my question but I can‘t find an answer to my query anywhere, so here goes:

When I opened Firefox on my Mac today (all up-to-date), a pop-up request by Firefox (cf. attached picture) showed up: "Firefox needs to download the font "Weibei SC". "Weibei SC" is 17,4 MB." with the options "Skip" and "Download".

Puzzled by this odd request, I wanted to skip it, but anytime I clicked skip the window would pop up again. I never clicked on download and I actually closed and reopened the browser, without having it show up again. I even restarted my device and reopened Firefox but it didn‘t show up again.

Now, I want ro believe that there is nothing to worry about, that it was a software blunder of some sort and that maybe normally it just installs fonts in the background without me knowing. But for the sake of my own peace of mind, I‘d feel more comfortable if someone who knows the software better than I do, explain to me what this was or might have been, and hopefully that it was nothing harmful.

Thank you!

I want to install the older version of Mozilla firefox for windows 11 in Spanish and Dutch language, please provide the link for Spanish and Dutch for ex. 125 version of Mozilla Firefoz

I installed a dev version of Firefox to test a plugin.

Then I uninstalled the dev version, but now none of my profiles on the regular version work...

Please help me, I really need my old browser history and cookies.

When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.

I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.

Thanks you and please help!
