I appear to have my bookmarks duplicated. Bookmark Menu list of bookmarks, bookmark 1

                                                           bookmark 2
                                                           bookmark 3 etc
                                                           ........
                                                           bookmark 1
                                                           bookmark 2
                                                           bookmark 3 etc

At a glance, the repeated bookmarks are the same, but I could have filed a new bookmark in either set. What can I do to stop these duplicates?

I on MacOS and I'm facing this issue last half of the year. As usual mac book user, I have many WIP items on my laptop, so I don't reload my laptop every day, even months it can leave without reloading.

So, after a workday I just closing it and come back tomorrow. When I back to the work and want to open new tab: Jira, Gmail, LinkedIn any other tabs - FireFox just keeping in loading state. In comparison, the Google Chrome that opened as well all the time but with fewer tabs, open the same links in seconds.

I though the FireFox is not latest version, and updating or re-starting of it, sometimes helped me to fix the issue. But now it seems stopped work either.

So, after a 5 years on FireFox I'm seriously started about my migration back to Google Chrome. I'm not sure that you can help me in this forum, but at least I would like to hear you option. Maybe anyone else have seen such behavior also and FireFox could find the issue

It seems that the bookmarks function and history files are possibly "in use by another app". I do not understand much of this. I think it happened after an update. I tried a restore point. I deleted the Icons file as it seemed that might be an issue and they would automatically update on restart. I called Dell support, they could not fix it, neither could my smart, younger friends. So after hours of frustration, I had to install chrome, which I hate. What I want is for someone to just fix it. Its 2:30am and I need to get some sleep, I will check this tomorrow afternoon and see if I can get anywhere. Good night all!

i re-installed my windows, installed firefox, and it automatically re-synced everything, a few days later, windows had an issue so i had to install windows again, but this time, when i installed firefox, i logged in, and after finishing syncing nothing was there, everything is gone, that being said, it's only form the desktop browser, i still have all my bookmarks and passwords on my phone's firefox, but they wont sync into the desktop one i cant find an option to export the phone ones into a file to import in the desktop app, i need help

Hi, my PC had some hardware problem and al its data was wiped as procedure, so i had to install everything from zero, this includes Firefox, and when i did so i did the same as usual, download it, open it and log in to sync my data, but there seems to be a problem, all my data is gone, it says its synced and i try to sync it many times, no bookmarks, no extensions, no passwords, nothing, this is my only account too. tried to look up solutions online and saw people talk about 'old Firefox data' folder that can appear on the desktop but nothing for me, tried to go to about:profiles and see what profiles i had and switch to see if its in any or if the folder appears but still nothing, i don't seem to find a solution, i only got the PC back at the end of December last year, and its as far as i can see my Firefox activity here, but I've always used this account and I've synced in multiple PC's with no problem i don't understand what is happening now. thank you

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.
