Firefox Community Forum

every time i launch Firefox, I get the banner prompting me to log in to network so i can access to the internet, i don´t understand it , cos I see that I am both logged in and connected to the net ?

I’ve been using Firefox regularly and overall the experience has been positive, but I’ve noticed a pattern during longer browsing sessions that I’m trying to understand better. When multiple tabs are opened and I switch between them frequently over time, Firefox sometimes becomes less responsive. Pages may take longer to load, scrolling feels delayed, and opening previously loaded tabs isn’t as smooth as it was at the start of the session.

What makes this a bit confusing is that system resources don’t appear to spike significantly, and the slowdown seems gradual rather than immediate. Restarting the browser usually restores normal performance, which makes me wonder if this is related to session handling, memory cleanup, or how background tabs are managed over time.

I’m not necessarily looking for a quick fix, but rather trying to understand whether this behavior is expected and if there are recommended settings or habits that help maintain performance during longer sessions. If others have noticed similar behavior or have insights into how Firefox manages extended tab usage, I’d really appreciate learning from your experience.

I lost my entire browser (bookmarks, extensions, accounts) by opening firefox twice. Whilst firefox was opening (very slowly due to my wifi) i opened it again, thinking it may have crashed, next time i opened it my entire browser was gone. How can i recover my data?

Facebook videos in Firefox stop playing when clicking the Windows 11 Start button or opening Solitaire (after recent update)

This issue has just started after a Windows 11 update and restart. It has never happened before. I usually watch Facebook Reels while playing Solitaire at the same time — yes, I know, I don’t have a life.

This morning, after the update and restart, I opened Facebook and started watching a Reel as normal. As soon as I clicked the Windows Start button to open the list of programs, the video stopped. I then selected Solitaire, which opened to the taskbar. I restarted the video, clicked Solitaire to open the game fully, and the video stopped again. As soon as I minimize Solitaire, the video resumes playing.

I’ve tried all the suggestions I could find via Google, but nothing has worked so far. Note that this only affects videos playing directly on Facebook — videos playing in the Windows Media Player Legacy video player itself are not affected.

Any help would be greatly appreciated… and yes, as mentioned, I clearly don’t have a life 😅 Link to video showing what happens when I select Solitaire in the Taskbar. https://drive.google.com/file/d/1oKLIl3I4f9lfTZvbU-9pJ1gMbOU7h0zm/view?usp=sharing

Regards everyone.

More info... I run two monitors and it seem if I click on whatever I have open in the second monitor the FB video stops. So something has changed after I turned my computer on this morning and updated Windows. I even did a System Restore to a setting two days before this new update and nothing changed still have the problem.

I can run Firefox once after starting the computer. If I close Firefox, I cannot run it again. Any attempt to start says there is an instance of Firefox running so it cannot start. I did some research and for that running the following yielded some indication of a problem that I cannot seem to solve.

>taskkill /F /IM firefox.exe ERROR: The process "firefox.exe" with PID 10220 could not be terminated. Reason: There is no running instance of the task.

Something appears to have left this PID so that the computer thinks it is running when it appears that it isn't there.

Please advise. [edited email from community support forum]

I cannot open the msn site , on my Win11 desktop using Firefox.

https://www.msn.com/en-us/weather

which is not down and opens in the Google browser. What can I check , this has happened off and on but is now broken this week. The msn.com site does open , but clicking on the weather tab still fails.

My firefox tabs have been constantly crashing over the last couple days. When I tried to diagnose issues in troubleshoot mode, they still kept crashing. Here are the most recent report IDs for the crashes: bp-06b1b48f-9213-4497-8398-a11890260130 bp-726d0348-6100-41cb-a298-909550260130 bp-ce8a6448-fcb1-4543-9ed4-275b50260130 bp-2c16e522-cd5f-4b9d-bb1e-6f18e0260130 bp-80520225-49fd-4f46-8453-58b300260130 bp-6c4bd533-ac96-44f0-9593-81ddc0260130 bp-a9573328-6e28-41d5-bd1e-91cf30260130 bp-3992c4d8-2a09-4fc4-a426-016b50260130 bp-2c7e318f-e080-4e56-84ee-63a030260130 bp-986e724b-2356-4790-9dc9-3687f0260130 bp-ae6ac0bd-b096-4212-8252-d55440260130 bp-4c8705f9-4529-405a-9d09-967b70260130 bp-a90c5596-f9cd-4d63-8fd6-a55c70260130 bp-fdf29d55-6cd9-450c-a552-7cca80260130 bp-519e5b29-a47b-4c65-bfda-c1f970260130 bp-fad47bb5-3880-4090-bdb7-b754e0260130

Any help would be appreciated!

Youtube has two settings that must be turned on for captions to show and start automatically when watching a video. "Always Show Captions" and "Auto Play Captions" and not be forced to be signed in to YT. Both settings must be checked off/turned on for captions to work and "set" in the cookies, for captions to work when not signed into YT.

Previously, one could sign in to YT, re-select the settings, refresh browser and then sign out and the captions would work when signed out and viewing YT content.

Since your update today, YT's "auto play captions" option is now missing when using Firefox, but not when using chrome, meaning when using Firefox, it can't be selected while using that browser. The result is that persons who choose to use Firefox instead and don't want to be signed in to youtube, not wanting our information followed in a non anonymous manner, can't use firefox to watch YT and still have captions working without having to constantly turn them on for every single video watched (that's where "auto play captions" came in).

Bad, bad move. On both mozilla's part and YT's.

While I like to have shortcuts for sites that I visit frequently (Amazon, eBay, bank, etc.), I don't like the fact that a recently visited site shows up among the four rows of my shortcuts every time I log in and go to my shortcuts. (My computer defaults to these shortcuts when I open up Firefox). Something new that wasn't previously there. I'm like, "okay, that's not something that I put there myself". Something that I didn't SAVE as a shortcut myself. It wasn't like this on my old computer. I had just the frequent sites that I WANTED to show on my shortcuts, not a new icon for a site I've visited recently. I unchecked the "Shortcuts" box in settings and sure enough, ALL my shortcuts disappeared. Had to recheck the box.

Am I missing something here? Why can't I have only the shortcuts that I want on those four rows and not have an icon for a recently visited site just add itself to my shortcuts? Just because I visit any particular site (whether one of my shortcuts or not) doesn't necessarily mean that once I leave that site, that I want it to show up in my shortcuts with a slightly different looking icon from my regular shortcuts, basically duplicating what I already have, but needlessly adding something that I didn't ask to save? For example, if I open up Yahoo to check mail, despite already having a shortcut with the Yahoo icon, the next time that I turn on my computer, I'll have a slightly different Yahoo icon that might now show "log in", as well. Ditto with other shortcut icons.

I hope all this makes sense. Can anyone explain to me how to fix this? Any help would be much appreciated.

Per [https://support.mozilla.org/en-US/kb/control-personal-device-local-networ...] I was looking for Settings > Permissions > "Local network devices" but the option was not present.

Looking at about:config network.lna.blocking I found it set to "false" by default. Only after I changed this to "true" did the UI shows the "Local network devices" configuration option.

Why is this disabled by default? Isn't this a security risk? It seems like users should be notified by default and have the option to block these requests.

It's becoming very annoying when I open up my Firefox browser only to open a page and there's BING sitting in the upper left part of the screen. I got away from EDGE because of its invading characteristics. I have checked to make sure my default browser is Firefox. And it is. So how do I get rid of them?

Appreciate any comments.

Thanks. Scott

Hi,

I have logged out from some device (laptop) today. I had approx 150 tabs over there I would really like to recover. Is there any chance to get them back?

Kind regards Grzegorz

Whenever you go to close a folder from the bookmark menu in the browser sidebar, having scrolled down due to a long list, the menu will not only close the folder but also make you click whatever was in that mouse position on the menu with the menu closed. This means closing a folder having scrolled down will cause you to potentially click open another folder or bookmark unintentionally. This is not an issue on the old bookmark menu, but using that isn't as convenient as the sidebar is.
