Firefox Community Forum

I recently got a new laptop with Windows 11 Pro. I installed Firefox from the Mozilla site. When I click to open Firefox, it takes a long time - 41 seconds to be exact. I uninstalled, reinstalled and restarted my computer. I cleared the cache. I tried to run as administrator. Not sure what else to try. As I wait for it to open, it reads "not responding" in the search bar area. Any ideas?

some items are large, some items are TINY. I have tried resetting my display setting scale, but the url bar, the menu where are my open tabs, the bookmarks toolbar, and some other things re TINY.

Hi, When I click on a link in ANY email, it says " Hmm. We’re having trouble finding that site. We can’t connect to the server at omxj86ebb.cc.rs6.net. If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I know I did something to make my computer more secure, but don't remember. Please help! THANK YOU!

Firefox closes my window too fast-feels like after seconds of inactivity. Can I extend to 5 or 10 minutes? I live alone so o no one is going to run in here and get on my computer when I get up to let the dog out.

Thanks!

I use Firefox for genealogy research because it always keeps track of which pages I've previously accessed since their hyperlink will change color. Today, I ran Microsoft's PC Manager software and it suggested clearing the cache of Chrome and Edge. For some reason it also must have cleared the cache of Firefox since the previously accessed hyperlinks are no longer a different color. Since I had a created a restore point this morning before installing PC Manager, I restored the system to that point. Following the restore, Firefox would not open so I re-installed it from the website. I had previously backed up the profile folder and so copied that to the new profile folder of the fresh install. My bookmarks and history seem to be fine but I still don't see a color difference in the previously accessed hyperlinks. Any suggestions on how to get them back would be greatly appreciated.

Using Ubuntu 24.04.3 LTS with Firefox 147.0.3 (64-bit)

Firefox crashes when trying to access any banking website. Can get to the login page, but then firefox crashes and a crash report window comes up with quit or restart option. This has been going on since shortly after upgrading from 22.04 Ubuntu. Started with Firefox 147.0.1 and after upgrading to 147.0.3 did not fix the issue.

Started Firefox in Troubleshoot Mode and that works when going to the bank login page. Using Standard Theme and only extensions Windscribe - Free Proxy and Ad Blocker and DuckDuckGo. Disabled both and same result of crashing om bank log in pages.

I run Windscribe VPN through my separate subscription, but it doesn't matter if it is on or not. Banking websites (Keybank, Kinecta, Capital Group) still crash Firefox

Also crashes when trying to access Excellus BCBS log in page. Most other websites (news, sports, Amazon) are fine.

Searches on your support page yields ) results.

Please advise!!!

I have an iMac M4 running Tahoe 26.2, which has an admin account and three user accounts. Last time I tried to open Firefox in one of the user accounts, it asked for an admin password to install a helper, presumably to update. Rather than responding, I switched to the admin account and updated Firefox manually, (from the "about" option). If I now try to open Firefox back on the user account, I still get that request, but even after I enter the admin credentials, Firefox won't open. It does however open on the admin account and the other two user accounts, not getting the "helper" window at all. I have reinstalled Firefox (twice), and removed the profile form the troublesome user account, but the problem recurs. Where is the problem and how do I fix it?

I tried starting Firefox in trouble-shoot mode, but nothing changed.

When I try starting Firefox from the Terminal with the -P option, I get the following message

I teach an online Adobe Illustrator Course. Students upload (.ai) Adobe Illustrator files. Not .svg or .pdf. But Firefox changes the (.ai) extension to (.pdf) upon downloading. This is HIGHLY irritating. Firefox, in prior versions, did not do this. In Firefox settings for Applications, there isn't a choice for .ai (Adobe Illustrator) files. I 'assume' that when AI (artificial intelligence) became available is when Firefox began automatically changing (.ai) files to (.pdf). PLEASE SOLVE this as I have to manually change the (.pdf) extension BACK to (.ai) HUNDREDS of times a day.

You did a new mozilla today and my bookmarks and bookmark tool bar are gone everywhere. How do I get back to profile yesterday 2/10/2026. It deleted my settings in TOOLs, Settings. Especially in security, how I want my home screen to look. This is horrible. Help.

I use Firefox on all of my computers and they all have a plus sign next to an open tab to open a new tab, but on this computer I have to right click on the 5tab bar to open a new tab - how can I get the plus sign to show for easy tab opening?

I tried to purchase something on Amazon. When trying to log into my Amazon account it asks to perform 2Fa on my mobile or use a pass key. But neither option responds and Firefox is completely locked up - cannot tab, select menu options etc. I have to use the Apple Mac Force Quit screen to kill it. But when I open Firefox again, the same tabs appear and it's still locked up on the Amazon screen. Cannot use Firefox at all now, forced to use Chrome. How can you reset FF. so that it just opens a new screen?
