I am trying to add custom search engines to Firefox. I have tried the steps given in the forum thread https://support.mozilla.org/en-US/questions/1212596.

However when I try to go and add the search engine as per the article given above I do not get the option. Please see the attached screen shot for more details. I do not want to add an extension or a plugin, but just manually have the option of adding search engines.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

When reloading a page, or navigating to a new page, the default Stop icon momentarily appears over my own Reload icon, and the default Reload icon also appears over my Stop icon.

Please see attached image and animation.

Any idea if this is a minor bug?

Below is my code to split the Reload button into Reload & Stop buttons, then to add text to the navigation buttons, and finally to add icons to the navigation buttons.

This anomaly happens whether or not I split the Reload & Stop buttons. With just a single Reload button, I'm also seeing the default Reload icon appear over my own.

Thank you.

I am unable to sync my Meta Quest 2 FireFox bookmarks and data with my PC Firefox browser I press "sync" on VR but nothing happens. I am signed in under the same account for both devices

New tab opens to blank page and not my home page, which is Google. I have been to setting and went to the drop down box for tab settings but it only gives me an option to make firefox my home page or a blank page. I want Google to be what appears in my new tab when I click on the little + isgn.

Recently firefox stopped filling in my credit card information. 1. On a website asking for a credit card click on the credit card number box. 2. Choose the car from the popup. 3. Popup disappears but nothing is filled in on the website form. 4. Use Google Pay or PayPal to purchase.

This used to work.

Firefox version 125.0b9 (64-bit) Ubuntu 22.04 Firefox installed from the Mozilla PPA - ppa:mozillateam/firefox-next

To check my icloud email, I log into icloud.com, enter my password, got through a two step authorization process and ask to stay signed in. I successfully access my email messages. When opening a message that has a hyperlink, I lose the iclolud connection. The link opens in a new browser window, but when i return to the email I am frequently signed out. Apple support does not know what the issue is; they suggested a different browser. This does not seem to happen with Microsoft Edge - and I don't want to use it.

Thanks for your help David Bartold; dwb0224@icloud.com

Ok-So this popup window popped up when I returned to Firefox. I don't think it's legit and I am wondering how I go about blocking it permanently. I searched the settings but didn't see where I could post the URL so that is why I am posting this here.

I copied the URL but I don't want to post it here in case it could do something to someone else's system. But here is the screenshot. Please advise me what I need to do. Thank you! TGIF!

I am on a Mac running Sonoma.

I keep hitting sites where menus and selection boxes turn into unreadable Wing Dings? On W11 and cleared and rest the font cache in Windows and still repeatedly seeing the issue?

I am using the apt version of firefox v125.0.2 (64-bit). I do not have a dedicated GPU - I use my intel core's internal gpu only Intel Corporation HD Graphics 620 (rev 02).

I used to play this game named narrow.one, which before I reinstalled the mentioned libraries, was working fine except for crashing a few times. I thought these libraries were causing some issue, so I tried reinstalling them.

I reinstalled the libraries using: `sudo apt install --reinstall --fix-missing libgl1* libegl*`

After installation, I start getting that error. So, I tried reinstalling firefox (using the same command), and then restarting the laptop - but of no use. Chrome seems to be running WebGL, including the game.

In firefox, on the https://get.webgl.org/ page, I see Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

After that, I also tried reinstalling `libopengl0` and `libglu1-mesa` and `intel-microcode`, but of no use. Running although, `sudo intel_gpu_top` and then chrome, it seems that the GPU is in use by chrome as well.

I then go to about:support. It shows me the images I have attached. Reading the logs, there several `blocklisted` values in `Decision Log` section. I suspect that's the cause of this issue, but then I don't know how can I un-blocklist the blocklisted things, and even after that, why does Chrome runs webgl if these are blocklisted?

Running `glxinfo -B`, I get the following: `name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer):

   Vendor: Intel (0x8086)

OpenGL ES profile version string: OpenGL ES 3.2 Mesa 23.2.1-1ubuntu3.1 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20`

I do not know much about OpenGL, but reading the above stuff, I suppose my GPU is in use and also has a compatible driver (although I am not sure).

Also, running `glxdemo`, `glxheads`, and `glxgears` seems to be rendering stuff.

Should I reinstall firefox after purging it first? Please help.

Thanks!

OS version : Windows 10 Pro 21H2 Browser version : Firefox Developer Edition 126.0 Beta 8 (20240501022718) Platform : windows, Web

EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

Need help figuring out why Firefox has a memory leak after an extended use of Firefox browsing. Don't know if its the result of an extension having this issue, or if its a Firefox bug. I have also provided my troubleshooting information, and a link to my memory usage is listed below for download: https://1drv.ms/u/s!ArspaZQCMwZ-iLU_CckOfLkl9DlETQ?e=MuIqsO Thanks in advance!

When I view my bank statement in Firefox, everything appears fine, but when I print the statement, all occurrences of boldfce "S" on the printout are blank. This problem does not occur with Google. Running macOS Catalina, all maintenance applied, Firefox is at 125.0.3.

I have used Firefox for many, many years and have always loved it. Recently, it stopped loading some websites. I have read and tried everything I have read and still can't fix the problem. I have to switch to Edge to load the sites. I am tearing my hair out trying to get this fixed, but I will have to use other browsers if this doesn't get cleared up. Some sites load and most don't, but there is no rhyme nor reason to what it loads and what it doesn't. I do not have a great deal of tech know-how and cannot seem to fix this according to my research. I get no "error" messages except that the page can't load. Please help. I would hate to have to learn another browser.

Please help. I have always been able to access Google Images when using my Firefox browser. Now I only get a limited few. For example if I am searching for images of Cedar Waxwings (a bird) I only see a limited amount of images and the word "Store" keeps showing up. Please tell me how to restore my otherwise satisfying experience of access all IMAGES. Thanks.

Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

• when I launch firefox normally (whatever the profile)
• when I launch it from the terminal (it provides no output at all)
• when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

• when I click "New Window" inside an existing firefox process
• when I call `firefox --help` from the terminal

Here's what I've tried :

• First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
• I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
• I've tried downgrading firefox (when using the package manager install) from v125 to v124
• I've also tried the Firefox Developer Edition, same problem here
• I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
• I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

• loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)

Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (I assume it's one of the options I have thru Firefox to block cookies), and I can't find where to allow cookies even if I did (I went to Firefox preferences etc) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to (try, I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you!

I downloaded the new update this morning and I cannot separate my categories any longer on my home page. I keep them in categories on the 4 separate rows and then separate them by skipping a square. I cannot do that any longer and do not like the jumble of the homepage now. How can I keep the blank spaces that are located at the bottom of the rows to separate my categories?

Since upgrading to the last version, 125.0.3 I'm getting tab crashes. Is there any way to go to a previous version? I have not had any issues with the websites I'm visiting until this new version of Firefox.
