I had a lot of tabs open in Firefox, and they always stayed there even after restarting my PC. But suddenly, all of my tabs disappeared, and I can’t recover them using “Recently Closed Tabs.” Can I get them back?

I'm using Firefox 129.01 (64-bit), trying to log in to my Tufts Health Plan account, and get a security warning (screen shot attached). Customer Service at Tufts Health Plan tells me that I should use Chrome.

Should I ignore the Warning and proceed?

Suddenly I cannot search from the search bar. It defaults to the address bar. why "fix" something that was not broken. Being forced to use the address bar is frustrating. If you go directly to the address bar, it tells you it cannot find that site.

On my Windows 11 computer messages keep cropping up supportably from Firefox. I have switched the computer off. this is from my old computer. I don't know what to do now. Colin

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Today I realized that I have installed two (2) versions of Mozilla Firefox on my Laptop PC which I rarely use.

Both editions are 64-bit type but one is version 109.0.1 (11/04/2023) in

C:\Program Files\Mozilla Firefox and the other is version 128.0.3 (28/07/2024) in C:\Program Files (x86)/Mozilla Firefox.

I suppose it is illegal to have two versions of the same App., so the question is how can I delete the old version (109.0.1) without affecting or damaging the new version (128.0.3)?

Thank you, JOHN HATZITOLIOS

I just started having an issue while watching Live Streams on Youtube with FireFox. I'll load the live stream and it will run for about a minute then it will switch to the streamers previous recorded stream. I opened Youtube on my iPad and on Edge browser and the Live stream keeps playing the live stream but on FireFox it only lets it run for about a minute before flipping the playback to the previous recorded video of that streamer. I tried clearing my cache for Youtube and I have no extensions running. I have Youtube Premium and run no adblockers. I have also tried safe mode but the problem persists.

Any idea what could be happening?

When I'm clicking "Copy Link Without Site Tracking" on Facebook, I'm getting a very long link like: [0=AZXHU5Fm3iETylzElY4qHRw27uWnI_VbYwCYYbj6x6BPjGaj_yfVTLR8fIvGILOGciQm0_XpeFu6uqxnV147PjmDPArCU4fCaydKmZ6_0BAp3j7mfUtGQhNPJQKsjPAK1sN0M7CjPgKHhIlL7_Mb2poXSVjQwF_nMhqHO7Xc_XTtdLQw9hxaPV5qUcKm8rbrWus&__tn__=%2CO%2CP-R https://www.facebook.com/PilsetaCilvekiem/posts/pfbid0EqFQ5TwTkHeowowTc7ArY8T7ATCjxXvWiUzXJeDxCjCcQHFwt4h8PK9eJaEiaYiml?__cft__[0]=AZXHU5Fm3iETylzElY4qHRw27uWnI_VbYwCYYbj6x6BPjGaj_yfVTLR8fIvGILOGciQm0_XpeFu6uqxnV147PjmDPArCU4fCaydKmZ6_0BAp3j7mfUtGQhNPJQKsjPAK1sN0M7CjPgKHhIlL7_Mb2poXSVjQwF_nMhqHO7Xc_XTtdLQw9hxaPV5qUcKm8rbrWus&__tn__=%2CO%2CP-R].

Would it be possible to remove URL parameters "__cft__[0]" and "__tn__"? Because https://www.facebook.com/PilsetaCilvekiem/posts/pfbid0EqFQ5TwTkHeowowTc7ArY8T7ATCjxXvWiUzXJeDxCjCcQHFwt4h8PK9eJaEiaYiml opens the same post.

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

I deleted all the shortcuts from Firefox desktop browser's homepage and now I cannot add them back.

There are no blank shortcut icons on the page anymore. No setting to enable them. Shortcuts are enabled. Page is mostly blank, only has Firefox icon.

I tried to close and open Firefox as well as disabling and enabling the shortcut setting. Adding more rows did not do anything.

Before this issue occurred, I had one shortcut on the page that was linking to localhost. I opened the edit window to the shortcut and pasted the same address and saved changes. After that I removed the shortcut. All of the blank tiles immediately got removed from page and I had no way of adding more shortcuts.

How do I get the + sign back on my tabs? After latest update I can only close tabs instead of opening new tab, and I am talking about after opening several tabs. When I have seven tab open, I have to do ctrl+t to open new tab instead of just clicking on the + sign that use to be at end of tabs. Yes, I do use custom settings. This happened before but I was able to fix by going to tabs under about:config, but it seems the setting is no longer there.

Youtube just does not run well on the firefox browser, I have had this issue on my pc, as well as my laptop. Twitch, piracy streaming sites, 9anime all work fine this problem with loading and buffering is exclusive to youtube. I have tried resetting my firefox settings, changing the values for load times and resource usage in about:config and none of these have fixed my youtube.I have tried multiple fixes I've been recommenced by online forms. I have switched my user agent to make youtube think I am using chrome, I have disabled and removed all of my extensions including ublock origin, and loading youtube remains painfully slow. In fact, disabling adblock makes the load times even slower.

Also responding to my post with "hmmm durrr it works just fine for me" does not help anybody, stfu.

What's up with this? Two fake Trust Wallet add-ins were disabled within the last couple of days after one stole my money and I reported it, and another similar one. They had been pinned to my toolbar and they were subsequently taken off from there with the message that they had violated Mozilla's policies. Now I see that again there are two of them. How can this be prevented? The most obvious sign that these are fake is when one goes to create a new wallet the add-in directs the user to import instead, i.e. it wants to steal private information like recovery phrase.

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.

Hello, I’m using Mozilla Firefox on Windows 10.

The issue happens mainly on YouTube: – Videos stutter every few seconds – Audio sometimes goes out of sync – This happens on 1080p and 720p – My internet speed is stable (~XX Mbps)

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.
