Firefox Community Forum

I use Mozilla Firefox for work. Part of my work requires I use the GlobalProtect VPN client. When I log on to the VPN, everything appears to be fine. The problem arises when I log out of the VPN client, such as needing to switch to a different VPN.

When I log out of the VPN client, Mozilla slows down massively. I get the following errors when trying to access websites.

PR_END_OF_FILE Timeout

I thought it was a DNS issue, but the change I made previously did not prove to be a reliable fix, and I do not actually know the root cause of what is happening. Firefox returns to normal ONLY after a full computer restart. At this point I am considering switching browsers as, despite Firefox's functionality, it is starting to interfere with my work.

I have used other VPNs, such as Fortigate VPN, and not encountered anything like this.

Any advice or guidance would be appreciated.

After my Windows 10 laptop being in sleep mode I found my background picture changed and all my Firefox tabs missing (while my bookmarks, add-ons, history etc. saved, and all other apps functioning properly). Recently Closed Windows menu was inactive and using Restore option in Library had no effect (despite availability of recent saves).

I found out that Mozilla folder was just missing in %appdata% (e.g. Profile Folder in about:support leaded to a non-existent directory). No manual changes to Firefox settings/data were made and no new profiles created.

What might be the problem and are there any ways to restore my tabs?

Hi there! My linux crashed and I only have an access to the terminal now. I'm trying to save login information and bookmarks that were saved in the browser. I didn't use an account. So I'm trying to find a location in the linux system where it was saved. I used 'find' command with key words 'mozilla' and 'firefox' to find possible locations but I'm not sure that I covered everything. Maybe someone here knows exactly where I should look. Thank you for you help and advance :)

I have 2 laptops, one for work and one personally. I was looking to set-up firefox on my personal laptop as well but noticed I cannot open developer console on a specific element by pressing 'q' anymore after right clicking.

This is a significant feature and I would like to keep using it. Is it possible to enable this feature on my personal computer as well? Since it is still enabled on my work device.

Every time I try to change the resolution of YouTube videos, it only provides 360p as an option, with a "Missing options?" message that redirects me to Google help page that just says my browser might be out of date (I'm on most recent Firefox and Windows 10 updates). The quality is still stuck in 360p when I reboot Firefox in Troubleshooting mode, and there are no quality issues when I use a browser like Edge. What should I be checking to resolve the issue?

I have two notebooks with Firefox (NB1 and NB2). NB2 rebooted and Firefox restarted losing all open tabs; now I would like to bring the tabs from NB1 to NB2; both have synchronisation enabled, but when I go to ‘Settings, synchronisation’ on NB2 it says ‘Synchronising in progress’ and nothing happens. I've also tried going to NB1 and sending a tab to NB2; I select NB2 and nothing happens.

This used to work fine. I don't want to mess with userChrome.css to get it to work. It should just work like it used to.

Thanks very much...

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

I was reading https://embracethered.com/blog/posts/2024/m365-copilot-prompt-injection-tool-invocation-and-data-exfil-using-ascii-smuggling/ and hovered over the hxxtp://wuzzi[.]net link.

I noticed that the status bar on firefox shows the same text as the on-page text. It doesn't render the unicode url in full. I tried finding a bug describing this, but couldn't find one.

I have Hulu live tv streaming and the video is not streaming. I get a black screen when I select a channel or an item from the library. This also happens when I try to stream local tv stations' 24 hr streaming sites. Other streaming services (Disney+, ESPN+, Netflix... etc) stream just fine. Hulu works perfectly in Microsoft Edge but I truly prefer not to use it. I've been using Firefox for years. This has happened after the latest update of Firefox. The update before this latest I experienced a similar problem and using the trouble shoot mode narrowed it down to a problem with Adblocker Ultimate extension. I deleted the extension and reinstalled it and the problem corrected. I did the same this time and no success. I have cleared the cache and reset Firefox and still the problem exists. TIAF any help.

I recently explored the backgrounds on Firefox. I choose one of the, because they look really nice. But after I changed my Firefox Data Collection and Use settings the background disappeared.

Why do you have to keep "Allow Firefox to send technical and interaction data to Mozilla" and "Allow Firefox to install and run studies" enabled?

Yesterday I was able to see www.wowpresentsplus.com videos without a problem, but today I'm getting the next error:

Unable to play video. Please try again in a supported browser.

I have the latest version of firefox. I've cleared the cache and so on. Any idea on how to solve this?

Hello, I use Ufile for my taxes. They weren't bad a few years back. For the past 3-4 years they have been a problem with their website not loading properly. They want you to use Chrome (as do more then a few websites). I don't like Chrome for privacy reasons. What do you suggest I do? Load Chrome for Ufile and then delete it. Can you suggest a tax website that works better with Fire Fox? Open to suggestions. Thanks in advance. Bob

I used Firefox and recently there is no audio on any of the websites I visit. I am using an ASUS laptop with Windows 11. Other browsers (Edge and Chrome) do have audio. I tried disabling all of the add-ons but it did not help. Has anyone else experienced this or have a possible solution?

when i visit sites like home depot, lowe's or southwest airlines the auto populate feature thinks I live in atlanta, but i live in new orleans...how can I correct this

Hi there, after turning on my computer in the morning, Firefox has been suddenly rendered utterly inoperable and pulls up a PR_CONNECT_RESET_ERROR for all websites. No matter what I do, including all other fixes previously suggested on the Mozilla forums and elsewhere, nothing seems to work.

Things that I've already tried and did not work include: - Pausing Kaspersky Internet Security - Resetting WiFi router - Switching to a different WiFi - Turning on troubleshooting mode - Resetting Firefox entirely - Creating a new profile - Reinstalling Firefox (several times) - Installing Firefox for Developers - Flushing DNS - Turning off proxy settings

I really don't want to be forced to use Google Chrome. Is there anything else that I can possibly do that can fix this?
