I press F11 to go fullscreen, but it only hides the bookmarks bar, not the searchbar. I also tried the button in the menu to go fullscreen, but encountered the same problem. I closed the browser and tried again, to no avail.

I've lost all my login passwords , bookmarks and every single thing that can be synced. For some reason I had to reinstall windows so I made sure that I had synced everything in Firefox. But when I reinstalled Firefox and logged in , everything was gone. There was nothing that I had synced and it wasn't there even in the restore option in the bookmark menu. Can anyone please help me to get my synced Items back?

IIRC, in v60.x ESR the icon at top used to display bookmarks by default, and you could also look at history. Perhaps I'm remembering it wrong (It's the icon that looks like 3 books with the 4th leaning to the left.

In v68.8.0esr which is now installed it shows "Recent Highlights". I want to get the old behavior back. The following will remove the recent highlights (except the title "recent highlights"). But the bookmarks are not shown unless I click on Bookmarks.

#appMenu-library-recentHighlights { display: none !important; }

How do I get the old behavior back?

I know I can add an extra icon (display bookmarks menu), but I'd still need the other one to access history. Perhaps if there were a History icon and a bookmarks icon, that would do as I don't use sync, and there is already the downloads icon, and I don't need the Pocket List.

I was using Firefox and my system was low on resources so it killed the process using the most memory which was Firefox. When it restarted every page showed up as garbage. I've cleared cache. I've refreshed Firefox. I've reinstalled. I've rebooted. Nothing seems to work. mozilla.org appears to work but every other site I try looks like the attached image. When I view the source of a page that looks like garbage, the source looks perfectly fine. I'm running 77.0.1 64 bit on Windows 7. Any ideas?

Why is my internet speed so slow in Firefox? Is there anything I can do to speed it up? My speed is 110Mbps faster in Google Chrome. That is doing numerous speed tests on both browsers. I have no extensions or addons running. I have the latest version. Any help would be appreciated, thanks.

Every since i installed the win 10 2004 build, my computers will hang up when i try to open Firefox. The CPU goes to 100 percent and the power level goes to very high. This happens immediately or sometimes within an hour. It tries to open but only gets a white screen and a not responding message in the title bar. I have to reboot the PC's to get them to work. If i don't open Firefox they will work. I have two other computers and the same thing happens on them. I have had to roll back to my last win 10 build 1909 on all three PC's. Anybody else having this problem? Thanks for any suggestions you have

As the Title suggests.

My Add-Ons are all removed from my Toolbar and stop functioning whenever I set my History settings to "Never Remember History."

I have tried uninstalling and re-installing the Add-On's, refreshing Firefox, uninstalling/reinstalling Firefox. But none of this works.

I want to be able to use my Add-On's AND have Firefox not remember my history. It used to work before, but now it just won't let me.

Any suggestions?

Every time Firefox updates it breaks my computer. Previously, an update wreaked havoc with my High Contrast setting. The last update prevented me from adding photos to my emails. Today's update broke my WordPress blog. I can't add links to my blog posts. High Contrast issues seem to have been solved, but I still can't add photos to my emails, and now the blog is broken. I've had to do most of my work on Chrome and Edge. Why do you keep fixing things that aren't broken? No other browser is as aggravating as Firefox!

The pop-out, mandatory search address bar is crap and everyone hates it, as witnessed by how many people immediately came to ask how to disable it when it was forced on us with 75.01, but the about:config fix of toggling browser.urlbar.openViewOnFocus, browser.urlbar.update1, browser.urlbar.update1.interventions, and browser.urlbar.update1.searchTips to false no longer returns the address bar to the way everyone wants it, which is to have a dropdown list of the most recently visited sites.

I don't care what company is paying Mozilla under the table to gain access to users' search terms-- it's Google, Google is paying them for that access-- and I don't care how badly Mozilla needs the money. Turning the address bar into a search box is crapulous browser design, full stop, and I'm uninstalling 77.01 and never updating this browser again if it doesn't get fixed.

Sometimes when I go to a website a completely new window opens in the background. I would prefer to keep all the windows open under tabbed browsing. I did a bit of searching, including searching for a help contact but I could not find an answer.

When I go to support, and type in "how do I find the current version of firefox for windows", I get: "Found 2923 results for ‘how do I find the current version of firefox for windows’ for ‘Firefox’ " but none address the issue of how to determine the most current version number. I notice Firefox says that I cannot upgrade, I must download a new version, with no explanation. The download is a version-unidentified executable called "Firefox installer.exe" I would consider this suspicious behavior in most downloaded software. What is going on? This seems like basic information that should be immediately available. I had a popup that said I am using the most current (71.0) version (I am using v 71.0), which appears to be incorrect. Googling this question has no Mozilla hits other than "Release Notes" which might lead one to guess 77.01, althoughn Wikipedia thinks just "77".

I had to create an account just o ask a forum question?

Okay, so i visit one of the German language news sites that i visit very frequently, but today i get this: https://www.bild.de/wa/ll/bild-de/privater-modus-unangemeldet-54578900.bild.html Even if i do what they suggest, open a new browser window so that it is no longer in private browsing modes, or if i untick that privacy protection shield at the very left end of the search bar - the dam site does not change to give me the actual contents. I also tried via login to the site, login works - but site still tells me i am in private browsing - but i am NOT. So, what can be done about this (oh, i also added this sites URL into the exceptions list - but, in the window for Exceptions for enhanced tracking protection i can not add anything, why not?? (it just says You’ve turned off protections on these websites) no sites listed no possibility to enter a site).

That is a lot of unwanted hassles i need to resolve this .a.s.a.p. Thanks for help Oh, no plugins that block ads either, i only see the H264 video codec, Flash and a "Widevine Content Decryption module from Google as active plugins.

I don't like the megabar, and I have looked around to see if there are any fixes for the most recent Firefox 77 update that forces that user to have it (like at least one other update, it just assumes that people like it). I have tried using the userChrome.css file, but that didn't work. I have also tried going into about:config, which also didn't work. Is there any possible way to say 'I never want to see this megabar again in my life'? Or a way to tell the devs that it should NOT be a default option on new updates? Or a way to turn it off that will always be around, unlike the about:config deal? Any help would be great. I attached an image of the megabar.

My health provider uses doxy.me for telehealth. Whenever we set up a session using Firefox on my laptop my healthcare provider can't see me on his end. I used doxy.me troubleshooter and it gets stuck at "loading video stream". Using the same laptop but instead using Microsoft Edge and the video works fine. I have used Firefox for other web conferences using Zoom and that works fine. Any reason why this is happening?

I am having an issue with not being able to make a payment on a specific site: www.walmart.com since upgrading to Firefox 76/77.

I am using:

Windows 7 on desktop PC

When on Walmart.com with items in the shopping cart, I have the option to "proceed to checkout." This usually loads a new screen in the same tab - not a pop up box.

This time, however, I only got a white screen with continually spinning circle.

Attempted fixes:

Verified with Walmart that they could indeed access my checkout Verified that I could access the checkout in another browser, Internet Explorer Tried turning off enhanced tracking protection cleared cookies Disabled ad blocker Unchecked Block Pop Up windows re-checked Block Pop Up windows and created exception for www.walmart.com Upgraded to Firefox 77

None of the above had any effect.

I have no Add-ons to disable. I'm running a pretty basic system.

I was finally able to make my purchase on a different computer that was still running Firefox 75. Thus, I have narrowed the problem down to the upgrades of Firefox 76 and beyond.

I was also able to make a purchase on a different site using Firefox 76, but I don't recall if that site needed to load a new screen for checkout. Still, www.walmart.com will not cooperate. Any ideas what else could be blocking this particular site?

I can't find a way to change the scrollbar color in firefox 73. The gery on grey scrollbar is very annoying because it's so hard to see. I tried to create chrome folder and tried to add various codes to userChrome. I also tried this: https://gist.github.com/Sporif/db6b3440fba0b1bcf5477afacf93f875 but it seems to not work.

On some pages the scrollbar color is fine, but on most pages it is the annoying grey on grey. I also tried disabling layout.css.scrollbar-color.enabled in about:config without any effects.
