Firefox Community Forum

Sometimes I need to open XML files on my PC or in a network folder. If I open the file in the first tab in Firefox, it displays a neat and formatted rendering that makes it easier to read. However, if I open yet another tab, it displays a sequential text file that's difficult to read. How can I apply the style of the first tab to all open tabs? I've attached explanatory images (I hope). The second image shows how I'd like the XML file to always be displayed, regardless of the tab's position. Firefox 149.0.2 on windows 11

The Firefox browser VPN option and toolbar button for Firefox 150 was originally showing up after a recent update (was not signed into the browser), but when I signed into the account as needed to activate VPN, the VPN toolbar button and options under security settings disappeared. I can't find the vpn button to add back under the 'customize toolbar setting' as suggested. And when I go under privacy and security settings, the VPN section is no longer there. How do I get the VPN options back? I tried signing out of Firefox and then back in. I tried disconnecting 'sync' from the computer and that didn't change anything either. I've updated the browser on all devices I'm signed into to 150.0.1. The VPN toolbar button or setting option does not show up on any device I am using. The only browser I initially saw the VPN options on was the browser that I wasn't initially signed into, and it disappeared after I signed into the browser with the account.

None of the suggestions at the following help page work to get the VPN options back in the browser settings, or toolbar: https://support.mozilla.org/en-US/kb/built-in-vpn?utm_source=www.firefox.com&utm_medium=referral&utm_campaign=whatsnew-150#w_turn-on-vpn-in-firefox

Hello,

Is there an option to view the text for the pinned tab? Or add a custom text for them? This is because i would have multiple pinned tabs with the same icon.

Is there any work being done to add the option to order the password autofill dropdown to order those entries by recently used rather than alphabetically. See screenshot

Title.

Keyboard focus properly defaults to the address bar for new normal windows, and new tabs both normal and private. It is ONLY in new private windows that the address bar does not auto-grab keyboard input.

The address bar is highlighted as though it SHOULD have input focus, but typing does nothing until I click in the address bar manually.

This is unfathomably annoying. I've tried fiddling with various settings in about:config, and I've tried running in troubleshoot mode to rule out extensions causing the issue. Also tried a fresh firefox profile and the issue persisted.

Is anyone monitoring this community? Has it been abandoned?

I've been having an ongoing problem. I fixed it myself, because after posting here, I had zero responses and didn't know what to do, so I messed around and tried things on my own, which seemed to fix it. But apparently, it is not fixed, and I still don't know what to do. A Firefox expert I am not.

Very simply, I use two different computers, each 2000+ miles apart. Each time, and this has worked for well over 3 years now, the entire computer is copied to a backup. The backup data is restored, the current Firefox profile, as well as the Firefox program. To repeat, this has worked for well over 3 years now.

In order to get the extensions working, that requires disabling and then reenabling each one. (Otherwise, Firefox will not access the internet.)

This time, the extensions were disabled and enabled, and everything appeared to be working fine, but nope, not a single extension works. Even choosing a different extension that is normally disabled doesn't work.

I used to use Adaware, which is on the disabled list, so I disabled the non-working Ublock Origin and enabled Adaware, and it doesn't do anything. The ads roam freely all over the page. They pop up and dance around.

Not one extension will work. New, old, enabled, disabled, whatever. Nothing.

Does it bear repeating that I am not a Firefox expert? Without an answer from someone who knows what they're doing, I may as well switch to crap, inferior Edge with the zillions of dancing, pop-up ads. And I hate Edge.

I'm begging for an expert to help here.

This problem has been covered in this forum before. However, the various solutions have not worked for me because it seems my backup previous.jsonlz4 was corrupted. I did exit Firefox normally, but I am not sure because I have been using multiple different browsers in recent months.

This is what happened this morning: my Firefox on Mac OSX was closed normally, and I rebooted the MacBook. Afterwards, I could not restore old tabs because "Recently Closed Tabs" and "Recently Closed Windows" are greyed out.

I tried copying recovery.jsonlz4 from the last folder and putting it into the main folder as sessionstore.jsonlz4, then reopening Firefox. Still have no restored tabs. Here was the surprise, which I do not know how to interpret.

I just checked some files and found this error message in sessionrestore-logs folder:

1770888233416 SessionStore ERROR SessionSaver write() rejected with error: Error: SessionFile is closed(resource:///modules/sessionstore/SessionFile.sys.mjs:424:29) JS Stack trace: write@SessionFile.sys.mjs:424:29 write@SessionFile.sys.mjs:47:32 _writeState@SessionSaver.sys.mjs:375:29 _saveState@SessionSaver.sys.mjs:308:17 _saveStateAsync@SessionSaver.sys.mjs:354:10 saveStateAsyncWhenIdle@SessionSaver.sys.mjs:194:14 requestIdleCallback/<@Timer.sys.mjs:180:15 observe@AsyncShutdown.sys.mjs:570:17

According to everything I CAN see, I have Firefox 150. I am still using Windows 10 and I don't seem to have problems with that. However, I CANNOT get to the Firefox Browser. I am very frustrated with only seeing Mozilla this, Mozilla that, but not Firefox. When I go to the help section I am able to click on Firefox Browser, so I know you still have it. The main item that is very different is clicking on Firefox to open it, and then seeing 3 different ways to login. I'm at a loss, and I'm frustrated. Please help me so that I may sign in to Firefox BROWSER.

By the way, when I click on Themes-Add-ons for Firefox and choose what I think looks like PINK, it isn't pink! It's a very strange purple color. I want PINK. Thank you, RhonCa

Firefox accounts renamed Mozilla accounts - What you need to know

i am using fox to open the zoom , but is not working

I am somehow getting the new letter rendering on Windows 10, most letters are very pale, 't' is bold , tabs pale , looks horrible. I didn't change anything. So, annoying, difficult to read. Please help.

I received this email: Do you want to keep your Mozilla account and data? Your Mozilla account is used to access free privacy and browsing products like Firefox sync, Mozilla Monitor, Firefox Relay, and MDN. We noticed you haven’t signed in for 2 years. Your account and your personal data will be permanently deleted on Friday, Jul 3, 2026 because you haven’t been active.

I use Firefox every single day. I don't understand this message. Please explain.

Thank you, Cathy

I'm trying to login into microsoft office online. It let's me click on the sign in button, a new window opens up but stays blank. I'm assuming that window is supposed to be where I can sign in. However it will remain blank for some time and then disappears not allowing me to sign in. I'm not sure if it was with the new update.

Able to sign in to Mozilla account, but cannot find Sync anywhere. Sync is OK on multiple other devices. System also seems unable to load 140.10 esr. Is it possible to sync on esr versions?

Hi, I just upgraded from Windows 7 to Windows 10 home. One of the things that has changed is that my downloads don't stay. After closing Firefox the download is there but if you click on it it says "File missing or moved".

Was searching internet for information and received a notice that Javascript had been deleted and/or was unavailable. Advised to go to about:config and follow the instructions to restore it. I go there and get nothing on restoring; but several items telling what about:config is and how to use it; which just keeps me cycling through. I use duck duck go as my search engine. I also recently updated Firefox. How can I get Javascript restored so I can get the information I'm looking for. I'm using an Samsung android cellphone.
