Firefox Community Forum

A few days ago, trying to free up some memory and improve my computer's performance, I deleted the cache and tracking cookies from Firefox (using AVG TuneUp). Since then, I can only load a certain, variable number of tabs and/or pages without every new or reactivated tab or page claiming to have crashed (although about:crashes says that no reports have been submitted). Restoring those pages seems impossible without restarting Firefox or the whole computer. The problem persists in Troubleshoot mode, but as far as I can tell doesn't affect Chrome, although that used even more RAM. I've tried culling open tabs (of which I still probably have far too many, but it's never been an issue before), using the OneTab extension to reduce them to lists of URLs, disabling and re-enabling hardware acceleration, updating Firefox, checking for file corruption and RAM errors and even uninstalling and reinstalling the program, but nothing's worked so far. What might be going on, and what else can I try?

I can no longer switch search engines via the pull down list available to the right of the search bar. I used to be able to switch from a list I set up in settings. I now have to go into settings to change my search engine. This is annoying. Also, recently, when I make my first search with Google Search I have to enter the search criteria twice. The first time the system just sits there with no response. The second time it responds normally. This is the same on both of my Dell Lattitude laptops running the latest version of Windows 11. I run NORD VPN and Trend Micro internet security

Last night, Firefox spontaneously stopped recognizing input from my Logitech M650 L mouse's side buttons used to go back and forward through the browsing history of the current tab. I've tried refreshing firefox, checking the mouse software, trying a different profile, trying firefox in safe mode, checked the firefox config and the mouse button inputs were set to "true", tried clearing the cache, and even tested on a website that shows you your mouse inputs and the side buttons were not detected at all, while all other buttons were detected fine. The side buttons work fine in all other programs and browsers on my PC: Windows 10 64 bit.

There was a brief period where they started working again last night, but seemed to stop upon reboot my computer.

OS: Windows 10 Pro 64-bit with all the latest Windows updates installed; running Windows version 23H2. Firefox release I'm having problems with: 137.0.2.

Just upgraded to release/version 137.0.2. The first time I open Firefox each day it takes about 2 to 3 minutes for ANY website to load. Sometimes when a web page does eventually load none of the images display.

I have tried same websites using Google Chrome AND Microsoft Edge. Websites don't have problems loading using either of those 2 browsers unless I have Firefox open in another window. If they load slowly, as soon as I close Firefox, web page load quickly in Chrome or Msoft Edge.

Not a RAM problem because I typically have around 20% of my RAM being used.

Did not have any of these problems using Firefox version 137.0.1.

UPDATE: Thought maybe it was one of my add-on/extensions so I checked for updates. Four needed updating. Made the updates and website still no loading properly.

My settings does not have an option to enable Firefox Labs so I can enable AI support.

• Firefox browser.preferences.experimental.hidden was set to true and I changed it to false with no change in results
• there is no "Firefox Labs" section in my settings anywhere and I've checked "General" and "Privacy and Security"
• toolkit.experiment is set to true
• browser.ui.experimental set to true
• labs set to true

Found redit discussion with the same issue, but no solution

According to this page the option should be in my settings, listed after "sync" and before "more from Mozilla."

I've attached an image of what my settings menu looks like. There is no option for the labs.

What else should I try/do?

Note: using Firefox on Desktop PC. Not a mobile device. My Firefox version is 130.2.2

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

My issue is that if I access the upper right corner of the screen, titled "Open Application Menu" and go to Settings I'm told my Browser is not the default AFTER THE PROCESS OF JUST MAKING IT THE DEFAULT.

It seems there is an effort to try and drive all of us nuts. This never happened before, and if it continues it will be the end of electronic communications (which it is suspected is the plan by those who engage in violence to achieve their objectives).

What I came here for was to have my settings, after the process (done many times previously) show a response in Settings that, "Yes" my browser (Firefox) is the default, which it did for a time today. Obviously there is no persistence.

When I got help on this issue previously, my response was I already tried that, and it didn't work. There used to be a lot of different browsers. Now I haven't come across any of them currently. Some are having great success in seeing to it that only their browser will survive. That seems like a "gangland" type of mentality to me.link text I believe I spent enough of my time on this issue and explained it in detail. There's really nothing else I can "contribute".

I, by the way, went to my Internet provider today who found an email under Preferences that she said had the capability to steel my emails. It had an extension in Australia (*.AU). If that has anything to do with this problem I'd like to buy a pair of handcuffs to see if that individual(s) being constrained from using a PC keyboard is a cure for this problem.

My Sync is all fouled up and I don't have a valid recovery code: 1) How do I erase all traces of Sync from my laptop, my Android phone and my Android tablet? 2) Exactly how do I set up Sync again? 3) How do I generate a new recovery code?

Thanks. After using Firefox for years, I still have trouble with the little things.

I enter msn.ca on an open tab, https://www.msn.com/en-ca is displayed in the tab window but no content is displayed. No extensions are enabled.

Works in Edge browser. Also doesn't work with Brave browser

English: Arch Linux, Firefox 137.0.2 (64-bit), with Microsoft Edge Stable and Beta installed, both prompt: Firefox cannot find the program that stores bookmarks, history, or password data.

中文： Arch Linux, Firefox 137.0.2 (64 位)，装有Microsoft Edge Stable 与 Beta，均提示： Firefox 找不到存有书签、历史记录或密码数据的程序。

It seems like after an update I cant connect firefox to my plex server I did a browser clear and it worked temporally but it started again. But it will connect if i use Safari Please advise Seems to be a Http Https issue

I will visit a site, say engadget. Then I can open another tab, and I expect when I type en or eng or engadge that it'll autocomplete to engadget, but it won't. For some sites, it works, for others, it doesn't. I'm a developer and am used to figuring stuff out, but no matter what settings I change it doesn't consistently work. I use Firefox on all my devices but on this one machine, it doesn't work. I've triple checked the settings. I am this close to switching browsers, it's so frustrating. Any ideas would be greatly appreciated.

having trouble getting into url from Fox News. after entering my email to receive a link to sign into the page I want, the little circle just turns and does not move to the website I asked for. It was working and now it doesn't. Jim

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 get an error message when attempting to load the PBS main page. It was working fine until yesterday and I can get on the site using bookmarks for different shows but cannot load the main page (even from within the site). BTW, using Safari the page loads as normal.

Below is the message I get.

Application error: a client-side exception has occurred while loading www.pbs.org (see the browser console for more information).

Can you help?

Thanks, EJ

Mac OS Ventura Can provide more info as needed

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

Hi! I have been using youtube and all of a sudden, without me restarting firefox I'm loading a video and it shows this blank screen in place of the reader. The shortcut for full screen mode is not working and other shortcuts don't do much. I've tried some options like disabling every add-ons including Ublock origin and restarting, also disabled hardware acceleration and restarted, checking for firefox updates, and I think that's all I came up with. I tried to do researches online but couldn't find something that looked exactly like my problem. I still followed most of their troubleshooting.

As you can see on this screenshot the add-ons are disabled. The rest of the page works fine, even the comments. It's just the video, as if the reader was not there. Also to note that the videos accessed since this problem appeared are not in my youtube history, as if they were never read.

Have a good day
