Firefox Support Forum

When I now open my firefox browser it will only open in a minimized window located in the upper left corner of my monitor. I then need to click the "minimize window to change to "maximize" and then click it to open the window to a full size screen. As I open new tabs after this they open in full size screen mode. But once I close the browser I have to start all over again. Is this happening because of the new update? Would appreciate your help please. Note: I did not take a full pic of my desktop, just the top portion that includes what I see when I open the browser.

show close button ("x") on hover over a tab without having it in the foreground. Basically I wish to have the middle mouse click ability with a mouse which does not have said button.

Good morning. My Firefox appears to have updated overnight and now my menu bar is a light grey colour instead of it's original black. I want to reset the menu bar colour to black because I now have no contrast between it and my tabs. I have searched the help articles but none of them tells me how to do this. I am directed down the path: settings> extensions and themes> manage your themes.

Unfortunately I can see no way to 'manage' this theme. I would mention that I am a native English speaker but any so called 'discussion' of this issue uses what I call 'geek-speak' which is unintelligible to a non IT professional.

I would be most grateful for someone to explain to me in simple terms (ie keystroke by keystroke) how to re-set my menu bar colour to black, whilst noting that the text for (file, edit,view etc) needs to then be white rather than the pale grey which it has become.

As an after thought, does anyone know which developer it is that thinks it a good idea to mess with my original view settings during an update. It is NOT helpful and, quite frankly, really annoying.

Many thanks in advance to you wizards out there Chris

I'm finding that Twitter is not loading in my desktop Firefox browser (89.0.1), and I'm getting the error "failedScript=polyfills". I do use an ad blocker, but it's turned off for Twitter, so I'm not sure how that could be the issue. I'm not having the same issue in Safari. Thanks for any help!

Hello. I am vision impaired and the Firefox 89.0 (20210527174632) does not delineate tabs in view any longer. Only the active tab shows the outline of the complete tab and I am having a terrible time seeing other tabs I wish to select. How do I return/restore former version of Firefox? Below are versions seen local on my workstation. Thank you for any help.

I had completed install of Firefox 89.0 (20210527174632)Details Installed on: June 1, 2021, 7:04:53 PMStatus: The Update was successfully installed

I require return to Firefox 88.0.1 (20210504152106)Details Installed on: May 10, 2021, 7:30:55 AMStatus: The Update was successfully installed

I made a payment online, & when I tried to print a receipt I got a notice that the popup was blocked. How do I unblock that? I wasn't aware that I have a block on this browser. Thanks for your help!

Hello Mozilla Firefox support, Can you help with the following issue? I'd like to use Firefox as my primary browser however it presents blurry letters, particularly the smaller the letter size. I am using Windows 10 Home, Firefox Version 89.0 (64-bit)on a Surface Pro 7. The SP7 screen presents clearly, however, my external monitor, a BenQ SW Series LCD Monitor has the blurry text. Thanks in advance for help or directions to pursue in fixing this issue.

I know this is an obscure question but it would save time typing it all in each time.

I would like to create a windows shortcut to launch the profile manager like so:

"C:\Program Files\Mozilla Firefox\firefox.exe -profilemanager" - but it says "the name specified in the target box is not valid. Make sure the filename and path are correct." It works fine without the -profilemanager part.

Maybe it would have to be a batch file I'm not sure.

Dear Community, after one of recent Firefox updates I experience an issue with text display on certain pages. Some text is not visible because it is white on white background. The text is there, I can highlight it. I am using latest Firefox release as suggested by auto update. This white on white issue is regardless of selected Theme, even in dark theme it is white on white. Please have a look at the attached screenshots.

With the latest update, my tabs are now a complete blank space with tiny little words. How can I get something back, like a border, to define them again? Thanks for your help.

Hey all,

I upgraded firefox to 89.0 (firefox for ubuntu). When playing videos it now uses RDD process instead of Web Content. The problem however comes from the resources "RDD process" uses. It is consistently at 100% usage of a CPU core and this is causing my fans to be really loud. I fixed this by changing media.rdd-process.enabled to disabled in about:config and this fixed the system resource issue but I don't think this is what is meant to happen.

As far as I know "RDD process" is meant to use the GPU. My computer has a dedicated GPU so I am at a loss as to what is going on here. Anybody who has any idea?

Thanks in advance.

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

When I use firefox on my main display (1920x1080 144h 16:9) in full screen there is a noticeable white line in the bottom, not using full screen fixes it, but a pain in the ass to resize it all the time. I tried using the browser on my secondary smaller display (1920x1080 60h 16:9) and there is no white line. This seems to be a bug, how do i fix it?

I cannot access to Facebook or Messenger on Firefox, when i open, Firefox said Secure Connection Failed. I got this error for a week,i have used Edge and Facebook still work,pls help me.

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

I used to use a lot the three dots next to a webpage to share the page via airdrop (to have it/share it with my own phone or others'). Now the three dots have disappeared and, although I read here that I could do that by right clicking the page, the option for SHARE does not appear. Can you please explain how to do this now? (I use a Mac).

I know that clearing browser cookie regularly is a good practice, but I am a bit curious if clearing out those session cookies is the same as if you log out of all the accounts manually.

Because logging out manually will make both local and server side session cookies invalid, thus log out safely.

Meanwhile clearing browser cookies only delete local side session cookie, while the session cookie on the server remains. Which means the session is still valid.

So do I clear browser cookies or log out manually if I want to log out of all accounts?

I am an older Firefox user and I often find myself enlarging and decreasing size of fonts on different websites to make them readable. Lately I notice I am having trouble with the fonts I am using so I need advice. What are the good fonts to use for Firefox? Also, what is the setting to adjust the fonts Firefox uses in the toolbars and address bar?

I am currently using as follows: Default: MIcrosoft Sans Serif (I like the clean lines of a sans serif, but I'm not wedded to any particular one. ) Size: 10 Proportional: Sans Serif Serif: Newsreader Sans Serif: MIcrosoft Sans Serif Monospace: Lucida Sans Font size: 10 Minimum size: 9

The problem I am having is that text in the address bar is often unreadable due to artifacts that look like a digital font, you know, the blocks? If I highlight the URL inside, the artifacts clear up. I reinstalled Firefox but that problem didn't go away. I need to know which font Firefox uses for that area before I can even begin to try to fix it. Any font suggestions are also welcome. I particularly would like fonts that are readable in many sizes and free of flourishes.

By the way, I chose the image of Google News because I also have trouble with alt text showing, I can't figure out how to get rid of that so any ideas are welcome. It's just Google.
