I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

Hi,

i have set my home page to blank. Recently i noticed, that when i start firefox and visit a site, my arrow history (i don't know what it's actually called; the linear browsing history you navigate using those arrows) has the blank page as first entry. I don't want that first entry. How can i get rid of it? (And why is it called "chrome://browser/content/blanktab.html"?) When i open a site in a new tab, i don't have that blank page entry in the arrow history. So it seems like it must be possible to get rid of it.

Same problem with private browsing. The first page is always "about:privatebrowsing".

I'm using Firefox version 108.0 on Linux Mint.

It's only a small annoyance, but i really appreciate being less annoyed.

Thanks

I recently upgraded my system and, after installing and using Firefox, I notice the Find (Ctrl + F) bar is now at the bottom of the window. Whereas, it was previously at the top (which is more like every other application I use).

After some head scratching and web searches, I remembered I had to fix this issue previously (after a Firefox upgrade some time back). The method to fix it then could be found here: [there a way to put the Find Bar at top] That link is of course to the same question asked 4 years back.

I have once again followed the procedure there explained per: • Access my Firefox profile folder. In my case:

  C:\Users\<Me>\AppData\Roaming\Mozilla\Firefox\Profiles\5ym42ewi.default

• Create folder therein called ‘chrome’ • In that folder create a file called ‘userChrome.css’ • In that file add text:

  .browserContainer > findbar {
    -moz-box-ordinal-group: 0;
  }

However, after doing that (and restarting Firefox), the Find bar stubbornly remains glued to the bottom of the window.

Can anyone tell me how to solve this issue?

As a separate note to the developers: This issue is long-standing, that a web search reveals is still relevant to many users. Any chance of considering making it a standard option?

Years ago the find bar was located at the top of a page. The somewhere along the line it was moved to the bottom.

Some good guys realized that's a problem for some of us and came up with code to put into a .css file. That was in 2017/18

The code has worked until last week ~2023/05/15.

Now the find bar is firmly planted at the bottom of the page...very awkward place for me. Makes edge look like something to consider as their find bar is still at the top.

I've check the code and no problems...I say it appears firefox is no long allowing this customization code to be used.

I've checked the knowledge base and the same articles from 2017/18 are still there...and the solution no longer work.

Does anyone have any suggestions? I hate traversing from the top to the bottom to do my work. The find bar at the top really made it convient and easier to do my job.

thanks for any help.

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

Firefox is using a massive amount of ram for an unspecified task, simply defined as "GPU" is the baked-in task manager. The attached image is after a fresh reboot, with Firefox consuming about 8 GB more than it reasonably should, with only three ish tabs loaded.

For the love of God, can someone explain who thought it was a good idea to remove the option to sort bookmarks menus by name? Please do not suggest users to open the All bookmarks and using the View > Sort option because it's not permanent, such useless option only applies temporarily while that window is open.

What version must I downgrade to in order to recover the bookmarks sort by name? Because of course the option won't be recovered. Kindly explain who, and why did you decide it was very useful for the end user to delete this option.

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?

Malwarebytes & Privacy Badger appear not to be working, though shown as 'enabled' in 'Extensions'. No blocked content is indicated. Adverts appear on lse.co.uk which can cause all four CPU's on Intel i5 to hit hi 90%. This problem appears to have started in this release.

Have disabled Privacy Badger and installed Adblocker Ultimate. This seems to have cleared the problem and Malwarebytes Browser Guard is now reporting results. Can't see how to mark problem as fixed??

A further observation which may be related to this problem. Response time seems very sluggish on FF 112.0.1

I have re-enabled both Privacy Badger & MalwareBytes and disabled Adblocker Ultimate. Both appear to be functioning now.

I have noticed that the WebExtensions process can consume as much and sometimes double the CPU & memory resource as that needed for the Firefox process. Is this to be expected? Do I need these extra security features, or are they built-in to the browser anyway?

When FF (113.0.1) is maximized clicking on the first (left hand) pinned tab does not open the tab. Hovering over the tab doesn't change the background color of the tab.

If I restore down the window, hovering over the tab changes the background color of the tab from light grey to a slightly darker grey and clicking the tab opens it.

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

I don't know if breakage is the correct topic. I keep Ring.com open to the dashboard in a pinned tab. A few days ago, I had viewed and cleared videos as usual and later returned to view new activity. The site requires logging in every 30 days and so seeing that I needed to do so was not a surprise. What was a surprise was that the login buttons were grayed out. I closed the tab, cleared the Ring cookies and cache and tried again. No luck. I wondered if there was some other setting that I didn't know about and decided to open a private window and try it there. To my surprise, it works. I'm stumped. I'll attach the raw data from the private window as a .txt file. Darn. I can only attach an image. Well, I have it available and can copy and paste it into a subsequent post if you think it would help

Have tried rebboted laptop run windows defender offline scan. Does not work on any of my accounts Same problem in Chrome and Edge!

With the dark mode of Firefox on Windows 10 desktop it is IMPOSSIBLE to see which of the several tabs is the one that is open.

I work with tabs not windows as I always need to see all the pages/websites open that I work with in one view, and so it is a hassle and nuisance NOT to be able to tell which tab is active, having to click through each one or guess.

It's one of those small yet significantly impacting on the user experience things which one would have thought by now Firefox developers would fix.

The ACTIVE tab needs to be in different colour may be on a yellow background with dark font so that people can EASILY find it with several tabs open on the screen.

Any thoughts on this? is there perhaps an option to enable it - which I am oblivious to?

thanks

Sometime in the past few weeks the quality of any video I watch from any source has turned awful. Too much contrast, too vibrant. I checked all my settings on my monitor, and all is as it should be. I'm a photographer and aware of image quality and settings. Still images are perfect and the monitor displays stills correctly. My monitors are working fine. When I checked videos via Google Chrome, they all displayed perfectly. So, I can only deduce that it's a Firefox browser issue. I haven't added any new add-ons or extensions. I know that the browser has updated at least twice in recent weeks.

I have attached a screen shot of the difference between a chrome and firefox video. Please help. I don't want to change to using chrome. Thanks in advance.

when playing videos, firefox makes the videos much darker and higher contrast than the original videos, as well as maxing out the cpu on my laptop when playing video, started a day ago or so.

We have set up exceptions for mail.google.com and accounts.google.com in Settings. Yet, Gmail is still asking for passwords to log in and saving them. I thought I had done all it would take to have Gmail remember them. Am I missing something?

Also, we cleared cache.

Thank you, Meg

What it says on the tin, booted up my computer, started Firefox, had it apparently update and then the tabs were suddenly like this. It's functional and just looks weird, I guess, but it really bothers me. Any way to fix it? Thanks in advance!

Please excuse me if I miss any details.... this is my third time trying to submit this issue.

I will just skip to the meat of it this time. I'm getting this error while working from my localhost. I have been working on a personal project for years with this set up with no issues until today. I can no longer click on the errors in the console log and be directed to the Debugger tab. When I click on errors, nothing happens. If I try to open them in a New Tab, I get the error below:

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (webpack) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

I have also noticed firefox does not even load all the files until I refresh it at least twice. Even when it is all loaded properly, the error persists.

I have tried: - restarting firefox - restarting my computer - clearing ALL cache and cookies - running firefox in safe mode - disabling all add ons - disabling performance mode (was already off) - checking network.protocol-handler.external.javascript = false (it is)

Let me know if there is any other information I can provide. I really dislike having to work in chrome for this so I hope I can find a solution as soon as possible.
