Most of the keyboard shortcuts are not working. Copy-paste works, but others for example, Ctrl + F doesn't work. Very confusing and frustrating. Attached is the screenshot of Browser Console and it does show missing attributes. Not sure if this is a browser issue (currently using 147.0.3 (64-bit)) or I need to make certain change settings. I would appreciate any suggestions to resolve this issue.

I am 70, sorry if I am not clued into all the latest. I have used Firefox forever because it delete cookies and tracking. Thanks for that. I had a update last night and now I can't get into my gmail account. Thanks

I went into settings and searched passwords. then clicked onto saved passwords and tried removing what I thought was the password for a site. However when I log into the site the password continues to autofill. I'm wondering if I'm not getting to the right spot to deal with autofilling passwords?

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?

I am using 147 ESR and when I go to permissions and block all cookies for the site plex.tv the cookies are not blocked. If I go to the URL field and select the lock, it shows "clear cookies and site data" which means the cookies have being accepted.

Why are the cookies accepted from the site when I have set cookies "blocked"
