Firefox-Hilfeforum

The permanent changes from a normal website to a text version back and forward is very annoying. Even when I watch a video in such a website it disappears and shows the ony some text information. Deinstallation and new installation did not help to solve this problem. Other browsers workfine. What can i do?

Been using f-fox for years . Suddenly at reinstall rec'v error message see attachment "firefox-crash-Capture" . After that firefox fails at run time see attachment "firefox-crash-Capture-II" then nothing works no clicks must use ALT F4 to exit.

Please advise.

For the past week the little tab that pops up when I close firefox that reads something like "your previous session closed unexpectedly, click here to restore" has stopped popping up. I am also unable to restore my previous session through the "Restore Previous Session" option in the options. Any advice?

Hi everyone, hopefully someone can help.

I have an issue with Firefox, I did read this aticle https://support.mozilla.org/en-US/questions/1273628, hoping it might solve my problem, but nothing in it helped.

I am running Windows 10 (all up to date) and Firefox (all up to date version 79). I have done a fresh install of Firefox and my addons. I have run a virus check Mcafee (full scan) and have run Malwarebytes and ADW etc. all come back clear.

My problem is with bandwidth. If I run Speedtest on Windows with no browser open, I get my full download speed 220 mbps. If I open Edge and run Speedtest I still get the same speed 220 mbps, if I open Firefox and run Speedtest, my download speed drops to 80 - 90 mbps (I get the same speed even if I load Firefox in safe mode). Can somebody help with why my browsing speed drops so much and is there something I can do to restore some speed. Thanks in advance.

just switched to 2020 MacBook Air. when adding a bookmark to the bookmark toolbar, the icon and name shows. How do I delete the name so only the icon shows? Not sure if it's part of the new touchpad or what!!!

Firefox extentions often ask for the authorization "Access your data for all websites". The description is "The extension can read the content of any webpage you visit as well as the data you enter there, e.g. B. Usernames and Passwords." Does this mean e.g. if I type in my bank account in a firefox browser window or a password for any other pge that this extension has access to this input/password??? Martin

Over the past 6 months or so, I've noticed that I occasionally get corrupt images where the images are replaced by semitransparent, randomly colored vertical lines, as seen in the provided screenshot. I am unable to reliably reproduce the issue, and it seems to happen somewhat randomly, but recently its started to occur more frequently.

I am on the latest version of Windows 10 Pro, and all of my drivers are up to date, to the best of my knowledge. I'm not entirely sure this is a Firefox-specific issue, and I seem to remember the same problem occurring in the default windows 10 photo viewing app, but I'm not certain about that, it might have just occurred when I opened my images for viewing in Firefox.

I appreciate any help or insight anyone can provide, thanks!

Firefox just started asking for a "master password", which I never established. When I try to uncheck "Use Master Password" it asks me to enter my non-existent password. Yes, I know it's now called "primary password" but I don't have one of those either. Running Windows 10, no AVG installed.

I had setup file association for html files to Firefox on Windows 10. Recently, when I tried to run Belarc Advisor, I received an error message saying:

XULRunner Error: Platform version '78.0.2' is not compatible with minVersion <= 78.0.1 maxVersion <= 78.0.1

I am able to temporarily resolve it by changing html file associations to Chrome but it seems like the issue is with Firefox installations. I had previously inquired about issues with Firefox automatic updating and was advised to do a complete install. I did that and am at version 79.0 at this time.

The following post indicates that XULRunner errors are caused by "Incomplete Update: The main reason for this error is an incomplete installation/update of the Firefox browser. Firefox is usually set to automatically install updates and this process can be interrupted because of bad internet or a sudden system shutdown or an antivirus. Whenever this happens, your Firefox update doesn’t install completely and leaves you with an installation with a mixture of old and new updated files in the Firefox program folder."

Is their solution the best approach to cleaning up this update issue?

If I want to change whether cookies are enabled/disabled on Firefox, must I sign in to Firefox and then change my settings, or can I just click on the Firefox icon on desktop, open application and change settings from drop-down menu without signing into account?

Firefox was working fine up until about an hour ago. In the attached image, you can see the bookmarks toolbar, but everything above it is white. There's no tab. There's no menu (File, Edit, View, etc.). There's no URL bar/search bar, and no little X to close the window when I'm done.

It is not in full screen mode, although if I hit F11 twice the menu, etc. will miraculously appear.

I tried deleting the xulstore.json file as one post here suggested. I tried refreshing Firefox.

I have a Windows 10 computer running Firefox 79.0.

Did I click some weird keystroke combination? How can I make my screen look normal again?

I suddenly am unable to access Twitter on Firefox, either when I use my bookmark for Twitter or when I search for Twitter on Google and click on the link to the main Twitter homepage. Nothing happens with either case. The other browser I use (Safari) has no problems accessing Twitter.

I followed the instructions on the help site. Went to preferences. Went to Privacy and Security.

But when I try to scroll down to find the Delete Cache/Cookies (or whatever it says -- I don't know because I can't get to it!), my laptop scrolls down to Sync, the next category below Privacy & Security.

I turned off the Mac laptop and turned it back on. nothing. Help.

I'm sure I'm doing something incredibly stupid and it's a quick fix. If only there were a phone number to call . . .

From a Mozilla Support page, " Firefox lets you import login information from a .csv (##..##) file. This feature is available starting in Firefox Version 80." I have the .csv file for my logins and passwords thru the export function. I can not get the drop down menu where I can select the "import from a file..." per the instruction in the support example because I am running Version 79. Many attempts to update to the latest version stops at 79. My help page for version states that I have the latest update --v79. SO--- any suggestions as to were I can go to download version 80. I am trying to transfer my logins from laptop 1 to laptop 2 without going thru the laborious task of entering each login by hand.

Colors are distorted in MP4 video as you can see in the attached screenshot. The distorted colors impact video on many sites including yourlearning.ibm.com, webex.com, twitter.com, mlb.com, etc. They do not impact youtube.com which displays video correctly. My Firefox version is 68.10.0esr (64-bit) and my OS is RHEL 7.8, kernel version 3.10.0-1127.13.1.el7.x86_64, Gnome Version 3.28.2

I have tried running in safe mode but the issue persists.

How do get Firefox to display MP4 video with correct colors?

Using Firefox 79 on Windows 10, all of a sudden I am getting requests to install an add-on identifying itself as slideclocks.com. I did not ask for it and every time I try to cancel by hitting the "Don't Allow" button, other windows pop up. It also seems to generate multiple Firefox windows, once I counted 18 of them. Doing an "end task" from the Task Manager doesn't help; they just pop back up. I tried reinstalling Firefox but the who process just repeated itself. I tried restarting with "firefox -safe" but that didn't seem to help. I also get a cmd window now and then with the same request to install slideclocks.com. Attached is a sample of multiple windows being generated by this add-on. So how can I get rid of it?
