I am receiving "The page isn't redirecting properly - Firefox can't connect to server" error messages. This happens on nearly every website repeatedly for the last six? weeks. It does not happen in other browsers i.e. Chrome. I click the "Try Again" button in the Firefox error msg popup window over and over, 3-14+ times, to get past the error msg and access the site. When I try to login to many sites I am kicked out to the same error msg. Also kicked out of sites randomly when trying to navigate to another page on the same site. I had Claude AI take me step-by-step through all of the trouble shooting and adjustments to various settings. All of my extensions are off. I have had my ISP re-initialize my modem and I've run antivirus scans, still the problem persists. (Strangely YouTube does not have these problems) I love Firefox. I've got it setup just the way I like it. I have been using it for 20 years and during those two decades Firefox has been stable and had only minor glitches. I do not want to change my browser. Chrome feels clunky to me. I'm attaching three representative screen captures of the error msgs. Looking forward to anyone's help.

The Firefox Color extension (which says "Official extension built by Mozilla.") has made it so that when I right click a link and select bookmark link, the menu for choosing which folder to place the bookmark is forced to be dark mode. Due to how few sites I use dark mode on, this sudden reversal of colors makes it hard to read. I tried changing every setting to blue but none of them seemed to effect it. I couldn't find anywhere on the extension page to ask about this without leaving a review so I found my way here. How do I fix this, and if I can't, when is it going to be fixed?

Auto updated to firefox 150 yesterday. What's new screen announced the rollout of the free in browser vpn had reached us (in Canada). Clicked the link to set up, went to screen to follow instructions. There's no vpn icon in the firefox menu bar, no matter what I do. (And I have done everything obvious.) Was the VPN not in the actual update I received or is this some bug/glitch? Thanks.

Hi All,

I have tried the new free browser VPN however it does not load pages if I am using a custom DNS (Quad9) and have DNS over HTTPS enabled. Is this expected behaviour and just a limitation of the VPN?

Any advice would be much appreciated.

'bold textHow do I remove the recent browsing button from tab bar. I get shaky hand sometimes and this annoying button messes Firefox up. It is the most annoying new feature ever.

I'm using Firefox v126. I'm searching through the add-ons trying to find a few that I like and most don't work with my older version of Firefox. So I click into the version history of the add-on and find an older version of the add-on that will work with the version of Firefox I am running. Except... I click it and I get:

"The add-on downloaded from this site could not be installed because it appears to be corrupt."

say what? ok maybe a fluke, so I click on through, older version, older version, still old version. All give me the same error. Okay, maybe its just the add-on, no, its literally any older version of any add-on.

No way all those versions of add-ons are "corrupt." I can download the .xpi, rename to .zip and view the contents. Anyone run into this particular problem before and if so, how did you fix it? I'm keen to keep v126 of Firefox and would like to use the add-ons that I like to work with it.

helloooo

i am experiencing an issue with firefox where backup (Firefox Backup) is not working since version 148.0

problem: - when I try to create a backup, i get the error: “Hmm, there was a problem with the backup. Please try again in a few minutes.”

what I have already tried: - enabled and disabled backup password - changed the backup folder/location - cleared browser cache - tested across multiple updates (issue persists)

- backup is enabled, but I cannot create one - the error occurs every time - restarting the browser and system did not help

Hi Can't enter text in a site message box.

Message box appears okay after a link render and isn't a pop-up. Other routine Firefox fields work fine, any site. Works fine with my Chrome install. No cursor in the box but all other box elements interact with the mouse, like format buttons, help, resize, colour palette, etc.

Never seen this behaviour before and I have no ideas. Just moved to 64bit v150.0 on Win10. Thanks Dale

I had a problem where FF 140.0 would not update, and in trying to get FF yo update, I used a re-install tool to which I was pointed in my problem report. This caused FF to wipe out my configuration, and I lost all my windows and tabs. I have gone to

    \Appdata\Roaming\Mozilla\Firefox\Proifiles\abnfpged.default

cleared all of the data therein, and restored that directory from a backup I made last Monday. But I cannot get FF to use that directory. "about:profiles" shows only two profiles, but the Profiles directory has five profiles:

03/10/2026 09:39 AM <DIR> qf00ka5x.default 03/10/2026 09:39 AM <DIR> v842ceue.default-release 04/11/2026 09:16 PM <DIR> .. 04/11/2026 09:16 PM <DIR> . 04/12/2026 03:08 PM <DIR> abnfpged.default 04/12/2026 06:29 PM <DIR> jdfj91sd.default-release-1775960183850 04/12/2026 06:48 PM <DIR> f1jq4mlq.default

Only the profiles beginning with "j" and "f1" are seen in the "about:profiles" screenshot I have attached. And I have attached a screenshot of my profiles.ini file. Also, in the abnfpged.default directory I restored, where is the list of all of my open windows and tabs? FF used to keep that in a sessionstore.jsonlz4 file, but that file is only written when FF closes. I tried to save a copy when I was having problems, but I stored the copy in the same directory, which FF changed during the re-install process. Here is my profiles,.ini file:

[Install308046B0AF4A39CB] Default=Profiles/jdfj91sd.default-release-1775960183850 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/f1jq4mlq.default

[Profile0] Name=default-release IsRelative=1 Path=Profiles/jdfj91sd.default-release-1775960183850

[BackgroundTasksProfiles] MozillaBackgroundTask-308046B0AF4A39CB-defaultagent=lnvi5jn5.MozillaBackgroundTask-308046B0AF4A39CB-defaultagent

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.

The Firefox installed on my Compaq CQ58 laptop automatically updated to version 150. I'm told by Firefox that there should be a button in the top right of the screen to activate the new free Firefox VPN tool. The button is simply not there ! How do I start the free VPN without the button ? I am located in France.

I have a paid VPN account with Mozilla which I use on all my devices. Will this newly introduced free version work on all of my other devices while using other apps or is this only for Firefox ?

In your information about built in VPN you state "To use VPN, you need to sign in with a Mozilla account. If you’re eligible, you’ll see a prompt in the Firefox toolbar inviting you to set up the feature."

I have a Firefox account and I live in Canada, but it doesn't explain what other eligibility criteria is required or why I'm not seeing the VPN setup prompt. I understand this is an experimental update that is still being selectively rolled out.

I am very interested in this feature and would simple like to know why it's not showing up for me after updating to v150. Do I need to sign out and then sign back in to activate it?

Thanks
