Hi I have lost all my browsing history and nothing I browse is saved. Also all my bookmarks have disappeared and I can't save anything even clicking on the star doesn't do anything I have quite a bit of stuff bookmarked, can you help? The browsing history and my bookmarks seemed to disappear at the same time.

please try and update for me i have tried several times and it keeps failing to update i have closed computer and cleared every thing and have tried several times and nothing seems to work it has asked me to update several times over the last couple of days but nothing is updating and i cannot play any music on Utube or even old music that i have downloaded long ago

i do not have anyone to help me on this i did try help line but i must be doing something wrong because nothing has changed

as in the title, my bookmark bar content becomes invisible the space of the bar is still there but its empty after i resume from hibernation , i havent witnessed the particular moment it happens, im simply confronted with that problem ever since i updated to this build

have to restart the browser for the bar to be populated again with my saved bookmarks.

The "other bookmarks" button and the arrow left of it are unaffected by this

I had to quit Firefox this morning because of a problem with my proxy and when it reopened it had updated to Firefox 139. In the process, I lost my entire browsing history and all open tabs from my previous session. Although in settings I have "Open previous windows and tabs" selected always, when Firefox restarted the browsing history was empty and "Restore previous session" was not an option under history, nor were "Recently closed tabs" or "Recently closed windows." I cannot locate any backup files in the Firefox library on my computer (MacBook Air running Ventura 13.7.5). I really need to be able to restore the previous session, please let me know if this is possible.

The Firefox version I used before was Mac version 136.0 After I updated to the latest version, I found that the fonts of the browser's tab bar, search box, and bookmarks became significantly larger. How can I change the font size?

I do not and will not use the sidebar/vertical tabs features.

Unfortunately, it seems that firefox has decided to reactivate these features with an update? This is unacceptable. I do not want my settings to be altered with a software update. If firefox wants to tell me about a new feature, feel free to make a dialogue bubble pop up (once) asking if I'd like to explore said new features. Otherwise, please refrain from altering my preferred configuration without permission or notification. Doing so is completely asinine at best and shows open contempt for your customer base at worst.

I do not wish to give mozilla/firefox another opportunity to make my experience worse, thusly I ask: Is there anyway to entirely remove/disable the sidebar/vertical tabs feature from the browser so that it cannot be reactivated without the specific actions of the user?

Firefox is not loading on my desktop full sceen. I can see a small page minimalized when I put my curser on the Firefox icon. This has happened once before and I had to uninstall and install and I lost a lot of settings doing that. Please advise. Picture on the left is what I see, not the other.

Hello: FF 140.b9 64b w11p. Are there ANY search engines (not nec browsers, just want to do a search in the address bar or search field) that do NOT go to an AI site to search? I want to minimize my use of AI technology, which uses extremely environmentally costly data farms. Thank you.

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

im using firefox on ubuntu, version 139.0.4. when i browse the internet using firefox, every some time the toolbar and the search bar "freeze" - i am unable to click anything, from the url, to any of the buttons. it takes up to like 1/2 minutes for the search bar and the toolbar to work again. i never had this issue before, neither on ubuntu (and other linux distributions), nor on windows...

All 4 of my Firefox installations started sucking big time recently. Unbelievably poor performance loading pages, which was working super fast before. Never had such an issue, running on 4 different, high performance PCs and having same symptoms, where I have to wait for Facebooks posts to load for minute or so. Youtube stops playing in the middle of the video. In meantime if I try same pages on other browsers everything works fast AF. I'm on 1000Mbps connection at office and 500Mbps home. Noticed massive increase in RAM usage, which used to be around 3GB, it is now using 6+. What has happened ?
