Firefox Support Forum

My windows install in my dualboot pc is unable to open at the moment, I can access the windows files from my linux. But i need the firefox data on that pc that I kept. I don't remember which email I used on that account so I'm kind of stuck on getting my data from online. Is there a way to recieve all the data from another drive without opening firefox?

Just switched to firefox as my default and found that I can't sign in to netflix. It always gives me the "incorrect password" message. I've tried resetting the password, clearing cookies, restarting, turning the DNS proection off, restarting my computer, etc to no avail. Anyone else have this issue or know a potential solution?

After Firefox upgraded from 114.02 to 115 menu and tabs background color changed:

FF 114: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-07-05-17-00-30-1a3adf.png FF 115: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-07-05-17-00-34-cba7e0.png

These are screenshots of active window. When window of v115 becomes inactive, background color changes to lighter, but still no visible horizontal line between menu and tabs. I don't use any additional themes, "System theme — auto" is selected.

From release notes for FF 115: For users with a Firefox Colorways built-in theme, the theme will be automatically migrated to the same theme hosted on addons.mozilla.org for Firefox profiles that have disabled add-ons auto-updates. This will allow users to keep their Colorways theme when they are later removed from Firefox installer files. I guess it is relevant somehow, but i never installed Colorways and don't know what is it.

How to make FF 115 look like it was in 114? I can see changes in `browser/themes/` in sources between 114.02 and 115. Is it possible to "extract" default theme from 114 and install/apply it to 115?

I use Firefox under Fluxbox window manager in Arch Linux, if it matters.

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

I am a UK user and have just installed and started to use Firefox on a brand new Linux Mint installation. As I am transferring from a Windows/Chrome environment, there is a lot of setting up to do. Firefox transferred most of the chrome info for me, and so I was able to get up and running with bookmarks and logins quite quickly. However, there is one problem that I can't seem to resolve.

I have been able to set up my credit card details, and these are prompted when needed, BUT, Firefox will not remember my name, email, phone or address. Thus for every form that I have to fill, I have to enter these details, again and again (and again).

I have looked at settings and see that the 'Autofill Address' option is not present (see attachment).

I have followed and implemented the fix proposed elsewhere, to update/add GB as an address format. This has not made a difference.

Can anyone please help.

Regards,

Mark

One particular website no longer works with Firefox. https://www.familysearch.org/mapp/ I had no problems with this website until a couple of weeks ago. I can use the website with no problem on other browsers. I have tried a clean re-install of Firefox and clearing cache, but still the website does not work. Any suggestions? Thanks John

I've been searching for a solution on HOW to edit HTML files (for websites) on my new laptop. I used to use IE11 (Internet Explorer 11), on Windows XP / 7 (32 bit), which worked spot on, the steps were as follows: (I write websites from scratch most of the time) 1) Click on, say, index.html 2) IE11 shows the actual page 3)Click on View/ Source 4)The source code shows up in Notepad 5) Edlt the code, Save and click Reload the webpage. You can straightaway see the changes.

Currently my new laptop runs Win 11 pro, Microsoft does NOT support IE11 anymore, I can however run IE11 as a add-on, BUT it does not work very well . I also tried a couple of free dedicated editing programs also, BUT they are exceedingly clumsy to use and can't equate to the old IE11 at any level. Somewhere I read that Firefox ( i have v115) can emulate what IE11 could do, hence I am on this forum posing the question, as i can't find the solution,

Anyone in the same boat?

Please share your ideas, Many thanks

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

I have four active Firefox windows, each with quite a few tabs. I have been closing and re-opening Firefox with no issue until today. Earlier this week I updated my Mac OS to Ventura 13.5, and Firefox was still operating normally after the installation (closing and re-opening with all windows and tabs intact).

Today however, when I restarted Firefox, no windows opened automatically. I closed and restarted a few times, and finally one window opened intact; however the other three windows (still dispalyed on the "Windows" menu) refuse to open. When I look at my Firefox app on my iPhone, it also shows all the tabs intact.

What can I do to get these to open? I am running Firefox version 115.0.3.

recently, website config.office.com shows blank by Firefox, even for a new fresh OS and install installed Firefox

also, I tried from my different clients, it's the same behavior， no matter Windows OS 11 10, or Windows Server 2016 2019 2022

it's able to load in MSEdge.

Hello,

I'm having trouble importing data I had on my account into the browser I'm currently installing on a new HP laptop. I logged in, but I can't see any of the bookmarks. I tried reopening the browser, hitting the sync button, reinstalling... Sync was working perfectly fine before, it was also transferring my config and extensions, maybe it has something to do with HP, as it automatically installed HP Wolf Security Extension. Would there be a way to restore all the settings I had before, taking in consideration that I logged out from previous laptop and I don't have access to it anymore, thinking it was all synced on the cloud?

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

i want to know if there is an addblocker built into firefox and if there is how do i remove it because im pretty sure it's messing with a website i use to watch anime

After removing elements from a website with another add-on, I'm left with a considerable white gap at the top.

I can manually change (pointless) the margin-top property to -100px, but how do I do this with the Stylus add-on?

Stylus doesn't like negative values:

margin-top -100px

10:20 Expected "{" but found "-100px".

Is there a lighter/simpler alternative to Stylus?

just happened today....only the AARP website is not using my browser Zoom setting of 120% it is using browser Zoom setting of 160% which is too large....I reset it on each page but it wont stay at my browser Zoom setting of 120% this happened a year or so ago....cant remember the solution

When I play a video in fullscreen, there is a strange black border that appears around the video which makes the content smaller than it would otherwise be. This border does not display in Safari or Chrome, just in Firefox. It also occurs in every media player I've tested, including YouTube and Netflix.

Annoyingly, I can't get this to show up in a screenshot. It seems like Firefox guesses the aspect ratio or resolution wrong when it puts media in fullscreen, and it has the effect of downsizing the actual interactive part of the display. Meaning, I can't move my mouse into the border area to take a screenshot of it.

I'm on an ARM Macbook running MacOS 13.5, if that matters.

Is this a bug, and/or is there a way to fix this?

trying to open 3d model on this site https://teemo.gg/viewer/league-of-legends/champions/katarina/0 its start loaded model but nothing was showed in browsers based on chromium everything works fine

I am currently fresh on Fedora 38 and Firefox 115 with multimedia codecs installed such as ffmpeg. I have problems playing videos on Facebook or Twitch, like in myday stories, reels, and feed. But in YouTube, videos plays perfectly so I think there is a bug going on here? I already tested turning hardware acceleration on and off but no avail.

No matter what I try, I can't allow any sites to present my screen or a window, I can't find an option in settings neither in the option to allow in the tab. The "allow" button is simply not available at all. How do I solve that? The problem happens in all sites that I've tried: focusmate, cofocus, discord, google meet, etc
