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.

On certain websites, I see that the background color of the new tab page replaces the default background color making the content unreadable, example:

If I browser this website: https://typespec.io/docs

Here's what I see (see the firsrt attached screenshot). Now, if I open the same URL in Private browsing, the background color changes too (see the second screeenshot). In the 3rd screenshot I'm adding the reference rendering, that's how I expect this website to render (Edge).

In the screenshot 1 and 2, the background color is exactly the same as the one used by the new tab page when I open a new tab.

Questions: 1) Why is that? 2) Can I change that?

Context: I'm trying to switch to Firefox (from Edge)

Hello,

It's been a while I wanted to try vertical tabs and now is is possible with FF. I was wondering if it is possible to merge the two top rows when using vertical tabs ? (The address and buttons row and the Windows, minimize, resize and close row).

When using horizontal tabs, the top row (minimize, resize and close row) is merged with the tabs row. But when using vertical tabs, you can a "useless" row that takes almost as much space as the horizontal tabs row, so vertical tabs doesn't make you gain that much browsing space.

Thanks

This is a recent problem. I used to watch Peacock on Firefox with my ad blocking extension. Now I cannot watch Peacock videos. The page My Stuff displays but once I click on a program or episode to watch, I get the error screen. (see words below) Even with no ad blocker, I get as far as an ad beginning, and then the error. I have already refreshed my browser. This did not help. I can watch Peacock on Edge. (PC windows 10)

ERROR MESSAGE: Something went wrong. Sorry, your system configuration is not compatible with Peacock. Please check the supported devices in our Help Center (6007).

Recently a new sidebar appeared on Firefox on my desktop. I actually really liked the change because I have wanted to move my tabs to the side for a while. I had tree style tabs installed and I was a little annoyed that I couldn't disable the tabs on the top bar. But now I can!

My laptop however does not have the new sidebar yet and when I look for updates it says there aren't any. My laptop has limited screen space and I much prefer to have this new ui choice but I can't enable it. I understand that they probably update new designs in batches to test the waters but is there a way to get around it and enable it on my laptop too?

I use the same Firefox account for both so it seems a little counterintuitive to have different experiences on different devices on the same account.

Also very much thank you for this change! It's something I've wanted for a while. I also have one little suggestion and that is to have the option for a similar feature to tree style tabs on the sidebar tab layout.

I am using VPN and have excluded FF using split tunnel, so I enabled Secure DNS in FF with Cloudflare. When I first launch FF, I get a blank page and nothing in the address bar. After that, I can open all webpages just fine. It's only that first page right when launching FF that doesn't work properly.

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me?

When I open up the Add-ons Manager it shows Window Titler is turned on. But Ctrl-Alt-T no longer works, there is no button showing for it, and it seems to be gone. A button for it does not appear in Customize Toolbar. It is the single most important reason I stay with Firefox. How do I get it to work again? Thoughts appreciated.

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.

Hi. I'm trying to troubleshoot failure to resume a download in Firefox and I want to see the HTTP headers just like in Network Tab of Dev Tools, but I can't find how to open Network Tab from the "Downloads" list. Is it even possible?

Hello, Since the version 128 (x86_64) on Windows 11, SSH links are no more opened with the user. The link tooltip at the bottom of the screen is showing the link without the user too. Ex: ssh://root@10.0.1.1 -> will open ssh://10.0.1.1 instead. Thank you in advance

I'm using Firefox 129.01 (64-bit), trying to log in to my Tufts Health Plan account, and get a security warning (screen shot attached). Customer Service at Tufts Health Plan tells me that I should use Chrome.

Should I ignore the Warning and proceed?

I have had it up to here with Firefox. I am madder than a hornet. Currently, I am unable to access my Outlook email and DirecTV in my Firefox browser, though I can in other browsers I have. Sometimes, I can't even sign into Ebay.

The DirecTV problem goes back at least 4 years to a different PC, so I have had this same problem on two PCs, therefore it can't be my PC. Besides, why can I access DirecTV on my Norton private browser and not on Firefox? I get the following error window:

    An error occurred while processing your request.

    Reference #219.b2173e17.1724008787.36e807

    https://errors.edgesuite.net/219.b2173e17.1724008787.36e807

The differing Outlook problem has popped intermittently over the past few months, but has happened more often lately. In that problem, the sign-on button is not activated.

Similar with the Ebay sign-on problem, except Ebay thinks I'm a bot and won't let me go any further than that perplexing error message.

I'm in the process of gravitating to the Norton private browser. I've already got all my bookmarks moved to that browser. At least Norton works for these three websites.

To put it bluntly, I think Firefox is a big stinking pile of horse manure. Firefox makes it EXTREMELY difficult to find out solutions. I believe Firefox actually WANTS it to be difficult to use. Why else would it be so hard to find out things? For example, instructions tell me to do something in some menu or click on some button, but the menu selections or buttons usually aren't there. I go round and round through the same blankety-blank webpages. I feel like a June bug constantly circling round a light. Even wanting to simply restore Firefox to original settings requires pulling eye teeth.

It took me over an hour to finally restore Firefox settings yesterday, which fixed things for THAT DAY ONLY. Today, the same problems cropped back up again.

I've had it. Unless I'm given some solution THAT ACTUALLY CONTINUES TO WORK, I am quitting Firefox.

Have a good day. I sure as hell haven't.

The bookmarks sidebar disappearing is creating inconvenience and I´m always having to use CNTL-B to recover it, even after I have selected View/Sidebar/Bookmarks which has a tick. Each time I change sites it deletes the tick.

I checked the about:config toobars and I cannot find it, or am I in the wrong place ?
