Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!

I cannot remove "Your browser is being managed by your organisation" and seems to be stopping the home settings saving. They simply revert back to the default (see image) when I restart Firefox. Not sure what is meant by "your organisation" as I am a personal user, not organisation. I'm the single user of the browser (e.g. just one user on my PC, which is me) and also Admisitrator. Can someone help me remove this. Thanks John

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

I just got a new computer and had my info transferred. It is probably the latest version of Firefox on the new computer now. On the previous version it seems like Favorites was spelled out toward the top of the page on the left hand side. I see now it is just a star icon. Is there any way to get it the way it used to be? I'm sure I will get used to it the new way, but I still liked it the other way. Thanks

After the latest update (124.0.2), two of my add-ons (Tapermonkey and Youtube Redux) are not working, even though Firefox says they're enabled, and it is giving no indication that the add-ons aren't working, no pop-ups to enable some permission for these extensions. Both of them reformat the layout of websites to make them more usable, and using sites without them is basically impossible for me. I have tried:

  • Restarting Firefox
  • Disabling the add-ons, refreshing, enabling the add-ons, and refreshing again
  • Checking for add-on updates (everything is updated)
  • Deleting and reinstalling the add-ons
  • Restarting my computer
  • Checking the permissions in the extension menu
  • Turning off all other extensions except for one of the ones with issues
  • Reading through the FAQs and help pages and following the instructions on some of them

Nothing has worked. Every time I reload one of the sites affected by this to check if it's finally worked, the site takes a very long time to load. Since these add-ons are for different websites and both aren't working, I know that the problem is not with the sites themselves. Thank you.

I had to reinstall windows 10, and then Firefox on my computer, after logging into Firefox on this fresh install (had to reset password), my saved passwords and bookmarks are not there. They still exist on my phone, and my phone is now asking for the new password to start syncing again. If I log in on my phone, will it sync the passwords there to my computer? I am worried syncing will cause the ones on my phone to disappear. Is there any way to export my passwords/bookmarks on the phone(android) to file? As a backup just in case. I logged in on an old computer thinking it would sync, even if it was out of date, but now it also shows 0 passwords saved.

Hi, Firstly I apologize because I'm not very tech savvy. My firefox browser has been taking ages to load. I've tried various 'fixes' over the last week or so and they don't work for long. I'm going down the 'try this' list and am at the 'clear junk in manage data' suggestion. Someone else had success with getting rid of a load of youtube saved junk. I'm in the Cookie and Site Data area, it says it's using 793mb of disc space yet when I tap on 'manage data' to try and clear stuff that area shows up as empty. I've searched but can't locate how to fix this issue. Or I might be missing something completely obvious. :/

My memory, and health, is not great so if possible I really don't want to resort to clearing everything and having to re-add log ins etc.

Does anyone know how to fix this please?

Thank you!

I'm not sure how this happened, but one of my firefox web pages keeps zooming in only on one website and the zoom refuses to reset no matter what I do.

For reference this is wikipedia. Every time I load a wikipedia page it loads zoomed in to 210%, which I will then have to reset to 100% in order to read the page properly. If I for some reason click on a link on the wikipedia page that goes to another wikipedia page, the zoom will reset again to 210%, which I will then need to reset once again. This happens also whenever I switch from the wikipedia tab to another tab and then switch back again. I do have an addon that changes wikipedia slightly (the Wikipedia Vector Skin addon) but disabling this addon doesn't fix the issue.

I went into about:config several times already and changed different settings to try and make it stop, but nothing so far has worked. I've tried resetting layout.css.devPixelsPerPx to 1.0 and back again to -1.0 and it makes no difference. I also tried changing browser.zoom.full to false and it keeps happening. Changing browser.zoom.siteSpecific to false does fix the issue, however it also resets the zoom I have on other websites that I want to keep, so it's not an ideal fix. I also cleared all my cache and cookies and it changed nothing.

Does anyone have any idea on why this keeps happening only with wikipedia, and how I can get this to stop happening? I assume there must be some internal setting that would need to be reset in order to fix this, but I don't know how to do it or where I would even go.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.
