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!

Linux User So. I recently followed a Mozilla guide, previously posted, and something that I did, or changed, I now have a very annoying "profile" name in the title bar. Further to that, I now have an additional menu option called "Profiles", with --"profile --Add Profile

Manage Profiles

I have never had or seen these items, except when I've moved my profile from an old computer to a new computer, using the console of "firefox -P" command.

It is becoming very annoying as I only have one profile, and I don't want an more.

Question. How to I block the display of 'profile information' ? Thanks

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.

hi i just install firefox and when I use messenger and put my cursor on camerra or phone I have the message voice- video call not available on this browser can you help?

I have a two monitor setup. Since I installed the new AMD driver (26.1.1), sometimes when I play a game on my main monitor, and watch stream on Twitch in Firefox on my second monitor, it can cause the PC to freeze completely. I hear the sound, but the image is stuck.

I tried to disable the hardware acceleration in Firefox, and it seemed like a good solution. But because of that (which is its function), sites became laggy.

Is this a Firefox, or an AMD issue? Or Windows (I'm on Windows 11 25H2)? I will try to install an older AMD driver, but honestly streams had became laggy before the driver update for me.

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?
