Firefox Community Forum

My setting for "Open previous windows and tabs upon startup" is no longer working. It always used to, for years! Now whenever I launch Firefox, I only get a single, fresh tab.

Please explain how to ACTUALLY sync my collections & bookmarks from Firefox on my Android Device with Firefox in a browser. I am signed in to my Mozilla/Firefox account, and have Firefox open on my android Phone. When I click on Sync on the phone, It says go to go to some address similar to firefox.com/Pair - but when I typed this exact address NOTHING happens ( I can't find it now, that page won't come up anymore.) I only get sent to the sync page of the web browser - When I click on add a device - NOTHING happens again. after 7-8 attempts, I FINALLY allegedly set up Sync using my email and password - but now I can't tell if anything is happening!?!

How will I know if things are synchronized? How will I access these bookmarks & history? Where do I look for it when in the Windows browser? NOTHING about this is evident or makes any sense. Nothing works as your instructions say it should. So here's my requests:

• • It would be REALLY helpful if someone would actually write out a description of what it Means to sync your FIrefox tabs and bookmarks across browsers - what is actually synced, and how can we access it? **

And my number one Question - **I have a LOT of bookmarks in "Collections" in Firefox on my Android phone. Can these 'Collections' be synced to the online desktop browser?** That is the main reason I want to sync in the first place - but I don't see Collections as an option anywhere in the Windows Firefox browser

I have "Open tabs in links instead of new windows" checked.

I have no plug-ins that would cause this.

I have experimented with the various, conflicting "about:config" directions given online. (Nothing works, so I have reset about:config to default.)

• It is also worth noting the Firefox Support page is immune to its own Dark mode. WHY.

I am going to switch to Opera, since it has none of these problems.

Before commenting or responding on this post, make sure you actually READ IT first. I am so tired of these online MANSPLAINERS being all, "Go to about:config and do blah-blah-blah," or, "This is what you do: Go to Settings > General > Tabs > make sure you check the box that says "Open tabs in links instead of new windows."

Seriously, way too many people online are like customer support agents on the phone: "Try unplugging it and wait 15 seconds, then plug it back in; try closing it and restarting it."

If anyone has any real solution, I'd greatly appreciate it.

I use Gmail, and when I receive a newsletter from the local government, Gmail does not display the images in the newsletter. I've set Gmail to display the images (photographs), so I'm guessing Firefox must have a setting that is blocking the display?

Continuously being logged out of Mozilla on Firefox on different PCs (same account). Mozilla will not accept already saved password. I keep getting prompted to change password. I "change" it to the original password. That usually (but not always) works. How to fix?

my firefox is taking forever to load any type of page, and in addiition the thunderbird is also slow. I re-downloaded mozilla, but it is still downloading so skow. just last two days, and when I say slow like 2 minutes to open a page. HELP

I was having an issue with pdfs on firefox; all my pdfs were showing up as black. To fix that, I refreshed firefox, which solved the problem just fine. Unfortunately, once I did all my extensions stopped working. The page looks like this.

For most of my extensions, I can just solve this by getting rid of them and adding them again, but if I do that for onetab I'd lose all my stored tabs. How can I get this back?

As of today, when I launch firefox, all of my tabs (which have been working fine for the last several days) crash.

By disabling all of my addons, I get this to go away - and by testing addons one at a time I am able to determine that: -Ublock Origin -Kaskpersky Password Manager Cause all of my tabs to crash.

Whereas: -Sponsorblock for Youtube -Youtube Nonstop Both crash if I visit youtube, but don't affect the browser otherwise.

So it seems like ALL addons are currently broken when they try to affect a tab?

Hi there,

I’m using the Firefox Multi-Account Containers extension and would like to remove a site that’s been set to "Always open in [X] container." However, I don’t see a “Manage Site List” option anywhere in the container settings as seen here: https://support.mozilla.org/en-US/kb/containers

Here’s what I’ve tried so far:

   I’ve clicked the Containers icon and selected the gear ⚙️ to edit a container.

   I enabled privacy.userContext.siteAssignments.enabled in about:config and set it to true.

   I restarted Firefox (with session restore on), but still no option appears to view or manage assigned sites.

I’m on Firefox Desktop (Mac), and I’ve confirmed that I’m using the official Multi-Account Containers extension.

Is this a bug, a UI change, or something I’m missing? I’d really prefer not to manually edit the containers.json file if there’s a built-in way to manage these assignments.

Thanks so much for any guidance!

While i was trying to search indeed for a job the site started having a glich loading . I'm not sure if that the best term but doesn't fully load. I have had this issue at least 6x in past five years on default firefox setting and if i changed a few to make more secure . When i use other browser that are not firefox based it is fine . It happens on librewolf as well

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

Здравствуйте уже месяц не могу загрузить свое видео на ютьюб. жду несколько часов и прогресс загрузки видео ноль. Другой браузер свободно загружает видео. Браузер мозилла удалял и устанавливал несколько раз. Помогите пожалуйста с настройками.

Hello, I have not been able to upload my video to YouTube for a month. I have been waiting for several hours and the video upload progress is zero. Another browser freely uploads videos. I have uninstalled and installed the Mozilla browser several times. Please help with the settings.

I use tiling for my windows. After minimizing and then restoring the windows, the tab bar is no longer displayed. If I don't tile the windows, this error doesn't occur. I'm using the latest version of Mint Cinnamon. This error also occurred in debug mode.
