Firefox Support Forum

This question is about the developer tools (inspector). Sorry if this is not the right forum. If this is not the right place, please specify where I can ask this question. I have looked around but this seemed like the best place to write this.

This problem started a couple a month ago in Firefox Developer Edtion after an automatic update (to either v82 or 83, im not sure).

This is what used to be the case, prior to the update: In the developer tools, in the inspector tab. There's an overview of the HTML-tree, and when you hover over an html-element in the tree, the correspondent element in de browser window is highlighted, and when you move your mouse the item will no longer be highlighted, since you're no longer hovering over it in the HTML tree. This is how it has always been.

The situation as it has been for 2 to 4 weeks: After selecting a couple of items in de HTML tree, and maybe editing some CSS, so just after normal use, The selected element will stay highlighted, even though I'm no longer hovering over it in the Inspector window. I added a screenshot to show what I mean. This bug is annoying because when editing CSS, I want to be able to clearly see the changes I mean, but now theyre obstructed by the highlight. Toggling developer tools by pressing F12 twice fixes this obviously, but only for a couple of minutes, and sometimes the problem return immidiatly.

This problem first emerged in Firefox Developer Edition about a month ago after an update. It really messes with my workflow, and I couldnt find a solution. Tee problem emerged on multiple websites (not just the ones a was developing, as you can see in my screenshot it also happens on the mozzila website) and the problem was the same accros multiple computers (all modern windows 10 machinary, owned by me or my collegues). So I stopped using Developer Edition, and switched to using 'regular' Firefox for developing, as regular Firefox did not exibit this bug. But since last week, after regular Firefox also got an update, the bug appears in regular Firefox aswell.

So here I am, an avid Firefox Developer Edition user, desperate for a solution. Ofcourse I already tried everything from reïnstalling, refreshing firefox, everything.

Thanks

Gmail will not load in Firefox, but will in Chrome. I've cleared my history, cookies, and cache. I made sure I had the latest Firefox update, restarted my computer, checked in internet connection, everything I could think of. There is no error message; it just stops loading and the page is totally blank, as you can see on the attached image. I've run out of ideas and know-how. Anyone else had this issue and resolved it?

I added the language/spell check to my work email (outlook.office). I follow the same procedure in my hotmail (outlook.live) and although I added them, it is not an option when I type a message. I use Firefox as a browser and cleaned the cache. Elizabeth

Is there a way of setting up Firefox so that when I Left-Click on an entry in the bookmarks toolbar it opens the page in a new tab?

I know I can Right-Click and choose from the pop-up menu to do it, but I keep forgetting.

Thanks, Jim

I really admire the Firefox browser for its many innovative and adaptive functions and applications that one can customize to their needs without sacrificing security and privacy. The one that I find extremely helpful the most is Dark Reader. As an individual who faces neurophysiological challenges from a traumatic brain injury from many years ago, Dark Reader has enabled me to enjoy working and reading on the internet without having to limit myself or wear super-dark lenses due to sensitivity. The app has worked for most other sites except this support site on the Firefox browser. Because I have to use Chrome for my job, I have tested your support page there with the same app and it seems to work there. Is there something that I am missing?

I've started using the beta version of firefox relay. I was wondering if the same alias can be used for multiple different websites? I have used it to login to one website already. Can I use the same alias for another website?

I use Firefox on a daily basis. It's open 24/7 on my PC and has 7 pinned tabs because I use them all almost everyday - they are mostly e-mail. It's set to auto-update and I think it recently updated to version 80. Ever since Facebook announced the removal of Facebook Classic and rolled out a Messenger update yesterday, I have been getting weird memory-related issues. Since I don't use Firefox exclusively, I just minimize it but it's always running. When I maximize it back to use it, the Facebook pinned tab does something crazy and all my other software start complaining that Windows ran out of memory and sometimes even crashing them though Firefox doesn't and the Facebook page looks garbled like its CSS gets corrupted. I am using the new Facebook - the one that looks like an app - in Dark Mode. The issue only happens when I use Facebook. The issue started happening yesterday.

Important note: this only started happening yesterday. The only thing that changed was the update to Firefox 80 and the roll out of the new Facebook Messenger update. This PC is rarely shut down. Also, when I am using the network (like downloading games from Steam or Epic Games or GOG Galaxy), the issue worsens and Explorer crashes and closes everything in my notification area.

Current workaround: I closed the Facebook pinned tab and everything seems to be working fine.

Specs: Firefox version 80 (no plugins) Windows 10 version 2004 Core-i7 4790K, 32Gb RAM, SSD + 19 Terabytes total HDD NVidia RTX 2070 Super with latest Game Ready drivers

I have a laser printer set as default on a Windows 10 laptop. In Mozilla, when I select print, that laser printer has the green default check, but Mozilla defaults to Microsoft Print to PDF instead. How can I get Mozilla to accept the default printer without deleting Print to PDF which I do sometimes use but don't want as default? Image attached--it auto-checks PDF but you can see the laser listed above it is the default.

The top of the Firefox screen disappears including the Menu, URL and the Bookmark bars, and is covered by a white un-clickable area. If Outlook is the window below Firefox and the location where the close "X" in Firefox is clicked, Outlook will close.

The solution discovered is to reboot Windows. I have also tried uninstalling and reinstalling Firefox with a new downloaded version, and running sfc /scannow, but these were not successful. A few times, the same problem was seen in Chrome and it may be a Windows issue and not a Firefox bug. The problem is typically seen once or twice a day. It is not a problem that turning off full-screen will solve.

One post with this problem was found on a search from 2017 but the thread was closed.

Any suggestions for a permanent fix would be most welcome.

When I do a search using the address bar, clicking a search engine won't take me to the result directly. Instead a blue box (e.g. @Google) pops up in the address bar, and I have to click one more time to do the search. But the Firefox installed in my office needs one click only (i.e. no blue box pop-up). Is there a way to prevent the blue box from appearing?

(Both versions of Firefox are up to date, 83.0 64bit)

I add Amazon Affiliate links to my website and they are not showing up in Firefox. They show up fine in Chrome, Edge and Safari.

Here is an example for one of my pages - http://campcampsite.com/camp-cookbook/

All I see are blank squares..

Help!

Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

• Running in safe mode

• Using a different profile

• Downgrading to an older firefox

• Changing allowed CPU cores from 8, to 4

• Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

I followed the instructions on the support pages to transfer my profiles from an old W7 laptop to a new W10 one. After the copying of the profiles to the correct locations neither Firefox nor Thunderbird would start complaining that they could not find the profiles.

What I did (same thing for Thunderbird) 1. Opened Firefox troubleshooting on the old W7 laptop, opened the profile folder. 2. Closed Firefox 3. moved two levels up 4. copied the Profiles folder to a usb drive.

On new W 10 laptop 1. Opened Firefox troubleshooting on new W10 laptop, opened the profile folder. 2. Closed Firefox 3. moved two levels up 4. renamed the existing Profiles folder to Profiles OLD 5. copied the Profiles folder from the usb to the same correct location on the new laptop

When I tried opening Firefox on the new laptop it would not open complaining that it could not find the profile. Firefox had opened correctly previously.

Then when I renamed the moved Profiles folder to Profiles NEW and renamed Profiles OLD to Profiles, Firefox opened normally on the new laptop.

Identical procedure and result with the Thunderbird profile transfer.

What should I do?

Thanks.

When I try to log into my AMEX account with FF, nothing happens. The screen refreshes itself, but no log in, and no error or other kind of message. I have entered my User Name and Password manually and using Auto fill, no success.

Logging into my AMEX account on Edge and Chrome, works fine.

Suggestions?

Hi, web pages often crash with the page below. This is happening since less than a month ago. Before, the same pages (i.e. ebay.com login page) didn't. Any idea? Thanks

New logo at top of home page. What's the quickest/easiest way to get rid of it ?

Rant: Why did someone think it was a good idea to put a massive logo at the top of the home page ? It serves no practical purpose and it forces link icons down so you now have to scroll "!!"!! There's always ******* one isn't there !!? - someone with a crap idea who thinks the world needs to see it. How many hrs worldwide is going to be wasted today by people like me trying to undo this crud ? This isn't the first time some ignorant little ******* has forced their crap on firefox end users.

Hello Can I deïnstall the add-on/ extention 'HTTPS Everywhere' because of your update Firefox to version 83 with the option for HTTPS only?

Hello,

The problem that occurs to me can be seen at the picture in the attachment. I have cleaned cash and cookies, but it did not solve the problem. Any idea how to solve this??

Some months before I used to have an page loading icon which was some dots, going left to right and backwards. Recently, I have got an hourglass which I didn't know how I got it and it doesn't look as neat as the previous one.

Hello, just an ordinary user here. I am using Firefox long ago, 'till I switched just today. I ran basic security tests until I got to http://whatismybrowser.com. It says that I'm still running on FF78 but actually I am on FF83 [https://whatismybrowser.com/w/N7QEGDA] .I refred firefox and reset to the default settings still, the problem persists. What is this all about? What am I should do? Thank you so much, I would appreciate your help.
