Firefox Support Forum

This is a problem I've had for a while and thought it would be eventually fixed, but no luck so far.

TL;DR - Almost every time I add or remove monitors my Firefox hangs.

More context: I use a PC laptop and constantly switch from using just the laptop screen to using just a set of two monitors, with the laptop closed. What I do is, I lock my machine, with Firefox open on the laptop screen, connect the monitors, close the laptop lid, and unlock the machine. That causes Firefox to hang and I'm forced to kill it and open it back again. It usually reopens all tabs without a problem but the issue is pretty annoying.

My current version is 125.0.2 and I'm sure the problem dates from several versions

After Firefox updates itself, the restarted browser session is unresponsive to mouse clicks - can't follow links, can't respond to UI dialog boxes, the browser is unusable for practical purposes. It's fixed after another manual restart. This unfortunately breaks all the streamlining Firefox has done to restore the session after an update, because none of that stuff works the same after a manual quit and restart. This is happening on MacOS, and it happens across multiple computers.

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?

After the latest update to 125.0.2 (64-bit) the browser works fine for a few minutes and then pages won't load. It starts working again after a restart [ for a few minutes]. I have cleared the cache & data. Chrome works ok.

I have an issue where I go to website and I get a message that the website is temporarily available. I cannot go to a different webpage for what URL I want. I believe this has to do with history. I suspect I can get past this by flushing the history. I can get to the website I want by using a different browser such as chrome. Ho do I fix this?

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

I am writing to report an issue I have encountered while using the Firefox browser. Specifically, I am unable to take screenshots on the website https://hescoebill.pk/hesco-mis/. This issue persists despite numerous attempts, and it seems to be unique to this particular website. Is there any other way to take screenshot of site? I really want to take a screenshot for personal reason. Is it not allowed from the site owner side or what?

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

Others asked and were pointed to extensions. As long as extensions get access to my pages, I'm not willing to use any. So, is there an option in advanced settings, to return to previously viewed tab when I close a tab? Thanks, Cat

Canvas is working on all other browsers normally, but when I try to login on firefox an error 403 message shows up at the two factor authentification step. I allowed popups already in this browser so that is not the issue.

Hello,

I like using Firefox browser every day. After installing and running Avast antivirus protection (program version : 24.3.6108 (build 24.3.8975.832)), Avast notification always show this message every time I start up Firefox : please check the uploaded images : FPA Scam.jpg.

I already checked the extenstion, the Settings, and the Advance Settings of Firefox browser. I'd like to know if there is any parameter related to engine.forexpeacearmy.com and it is enabled. Unfortunately, I can't found any related parameters.

So, I decide to contact Firefox support to find out what happen to my Firefox browser, why it always call the forexpeacearmy site at the start up, and finally I want to remove it. Because I'm affraid it could be some kind of trojans / malwares and put my laptop into risks.

Kindly need your advise. Thank you.

Kind regards, Gideon

I find it very difficult using Awsome screenshot, in fact I never use it, but used to use it, when it was on my tool bar, can I get it back there.

I cannot drag it from "customise tool bar" as it does not show there, it shows in my list of add ons, I have tried removing it, then reinstalling it.

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

After installing Firefox on a new computer, where everything worked fine, I installed a number of fonts. Afterwards, all of text within Firefox appear to be in some version of Arabic. I have tried resetting, deleting and reinstalling, changing the Firefox language, and deleting fonts. None of these seem to work. Firefox is set to English US.
