I uninstalled Firefox which I had used for years because when I tried to open it it said the file was corrupted and unreadable. I installed firefox today but it didn't import my bookmarks. I use windows 10

all drop down menus such as donwloads/history/extensions/application menu suddenly have turned from dark to white in all of my created themes. I have not made any changes to my computer system, it's set to dark, firefox color scheme is also set to dark, I've tried automatic, played around with different combinations, that didn't change anything, and I've tried changing it in about:config, and everything in there is already set to dark.....i've no idea what to do at this point. I've reposted a few of my themes, hoping they would update back to dark, but that also didn't work. I'd really appreciate some help with this!

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at allI am at a bit of a loss, any ideas?

My computer use to start up in Yahoo, now it starts in Google, and I have to open Yahoo from Google. How do I get it back to starting up in Yahoo?

This was my fix for scrolling not working when hardware acceleration enabled. Upgraded this software product: X-Mouse Button Control (of Highresolution Enterprises) to latest release 2.20.5

TL;DR: Moved firefox browsers, didnt properly export passwords, uninstalled other browser, had logins.json from profile folder, needed to know how to import manually.

Fixed. I just installed the older browser, and properly exported the passwords this time.

New user here. My web search results dont fill the screen, they always require scrolling down to see the whole page at once (as designed). why are the top 2 bands 3 times as tall as the font in them, they use up valuable space. see snip insert below. i have trouble enough with windows 10 without squinting and all this needless scrolling down looking for the rest of the buttons. I use LastPass and its truly infuriating how big the boxes are and how hard to find the information, particularly the "go" buttons. TYIA Shandy

Hello. I have had Firefox as long as I've had my computer. I was on it today, and BING appears!!! I don't want BING. I really Like Firefox. Can you please help me? I don't know why it changed to BING. Please HELP ME. I really enjoy Firefox/ Moz://a . Thank you so much. I hope to hear from you soon.

This problem started with an update a couple months ago. Each bar is about 4 pixels wide and appears only on the right, left, and bottom edges of the browser window. They persist when the window is full size or smaller, but disappear on f11. The bars are completely unresponsive. Clicking or resizing the window doesn't seem to work inside of them. Even though the top of the window has no visible bar, there is still an unresponsive region like the other three sides and approximately 4 pixels of empty space.

When it comes to color, the bars spend about 50 percent of the time as white and 50 percent as the same gray that Firefox's dark mode uses. I wasn't able to get a screenshot when the bars were gray, but I was able to screenshot the top right and left corners when the bars were white, which I have attached.

It appears as if there are buttons of some sort poking out on the top right and left corners. If I had to guess, the top right icon looks like the "x" button on a Windows 7 window, and the top left icon looks like the red dot in the uppermost corner of a macOS window. My machine has only ever run Windows 10, and Firefox is the only application that this problem occurs in.

Restarting, using troubleshooting mode, manually removing extensions and themes, messing around with compatibility settings, running as administrator, refreshing Firefox, and reinstalling Firefox have all been unsuccessful. It really is annoying to live with this bug.

I don't want to save my Firefox profile on removable media and leave it accessible to anyone around the house. I don't want to use my iCloud to store it either, because files in iCloud drive aren't end-to-end encrypted; they're encrypted, but Apple holds the keys. I can store attachments in Bitwarden, and my plan comes with enough room to store regular backups of my Firefox profile. If I want to attach the entire profile folder (not all the individual files separately) in one shot, I have to make a zip folder first, and then I can attach it to the Firefox log-in entry in my Bitwarden password manager. Will the backup work correctly if I store it like this? I mean, if I restore a backup after extracting it from a zipped file/folder, will it work correctly, uncorrupted, etc?

Thanks in advance,

When double clicking on an email msg in Outlook, Firefox opens a new pop up screen, but it is blank. Using EDGE (and with same add ons), and doing the same thing, it works and am able to see my email message. How come Firefox doesn't do same?

How do I stop the Firefox Privacy Notice Page: https://www.mozilla.org/en-US/privacy/firefox/ from opening in a new tab, each time I click on the home icon on any other tab I have open. This is quite annoying.

When I read content on a web page, I like to use the up and down arrows and PgUp PgDn to go through it. I hate having to reach over for the mouse and line everything up to go to the next screen. Since the last update, it seems I can't do that. When I hit the down arrow, or the PgDn key, it skips randomly down the page. This is especially true if I am reading an article with pictures in it. I think this might have something to do with my clicking yes to an inquiry from Firefox that just appeared on the page while I was browsing. It asked whether I wanted to be able to block text with keyboard commands. I'd like to change it back to whatever it was before, but can't figure out how to do that. Bill

When using Firefox on my PC I am usually (not always) unable to load email content when using icloud.com. I am signed into my icloud account in Firefox and am up to date with Firefox. I can see email content when using Outlook, when using ios on my iphone and ipad, and even when using icloud.com on my ipad. Just not when using icloud.com on my PC. What gives? This used to be an occasional thing and has now turned into an almost always thing.

Hi,

I want Firefox to save files without asking. I need it for E2E test automation, recentyl something has to change in update because even in GUI I don't see an option to remember my choice. In case of E2E framework I had a setting which was working but now stopped to work:

desiredCapabilities: {

               browserName: 'firefox',
               alwaysMatch: {
                   'moz:firefoxOptions': {
                       prefs : {
                           "browser.helperApps.neverAsk.saveToDisk": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
                           "browser.download.folderList": 2,
                           "browser.download.dir": downloadsFirefoxPath,
                           "browser.download.lastDir": downloadsFirefoxPath
                       },
                       args: []
                   }
               }
           },

How to do it today?

I got Firefox 94.02 just some days ago, it changed from 94.01. Until the change all was in order, since I can`t dowload pics as JPEG or PNG anymore directly, but 94.02 forces me to donload as WEbP, which inconvenient. Can somebody offer help, or at least an idea how to fix this issue?
