The file-picker (when I choose any file related operation such as Open File, Save As, etc) on just one of my machines is far larger than my desktop size (and the window appears not to be resizable).

When I trigger any such operation I'm presented with what looks like a blank screen as I a shown part of the vast unused area of this oversized window. If I force my wm to allow me to move the window I can use the file picker with a lot of painful repeated scrolling around but otherwise it's unusable.

Any idea why firefox might be doing this or where it might have cached the file picker size? There doesn't appear to be anything related in about:config or userprefs.js

Starting up in trubleshooting mode doesn't have any effect on this.

Suddenly, now on FF 119.0.0.1, JPEG Images no longer open in new tab when clicked with mid-mouse-button (previous behaviour, wanted), instead they get downloaded, safed to DL-folder, and maybe opened in 3rd-party-app. I tried to change the Open-with settings, but to no avail - there's no option to 'Open in Firefox'/Internally. (Only Open with../Download)

I've tried older guides on the topic, which didn't apply here it seems, also cleaned cache, etc.

Hi there. I thought for sure this used to exist, or maybe things have changed? I am thinking I used to be able to hover over an image url in the source code and it would list the intrinsic image dimensions below the preview in the source code window. Maybe I was imaging this?

Thanks for your time.

On chrome I have several profiles and different ones use different LastPass (and other) extension services. EVERY PROFILE maintains it's OWN login information.

Firefox, however, does NOT ISOLATE PROFILES. On ANY Firefox profile, if I log into LastPass EVERY PROFILE is forced to use THAT information- even going as far as logging out and logging into the OTHER profile's information/account. This is 1990's level idiotic.

WHY are profiles SHARING LOGIN INFORMATION!? This is entirely stupid and defeats the entire purpose of multiple profiles.

I had this happen with Facebook logins, too... WHY does ONE profile FORCE OTHER profiles to change their login information?! WHY ARE THEY NOT SEPARATED?!

How do I solve this?!

it is the SINGLE biggest reason why I can NOT switch to Firefox again. Chrome does this. Chromium does it. EVERY Chromium browser does this. 10 years ago Firefox did this... and I left it when it QUIT doing this... when it BROKE profile separation.

Why is this STILL a problem?!

Amazon Prime Videos will not play on Fire Fox. The message says to update Firefox, but my browser is up to date as of today, 10-24-23. Their customer service can provide no answer. This has been an ongoing problem for several months. I have tried their trouble shooting steps of restarting my system, signing out and re-signing in on Amazon and closing and re-opening Firefox. Allow DRM content is checked on my settings. Thanks.

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!

About a month ago, I had no issues taking a screenshot of what's displayed or entire page. Now, whenever I take a screenshot, it copies only 3/5's of the page (from the left margin to roughly 3/5ths of the page both displayed or entire). My settings in about:config have not been changed (well, they are changed but at the same settings as when 'Take Screenshot' worked and now only copying 3/5ths of the page).

Having a hard time trying to figure out why Firefox View would be completely empty every time I check it (see attached image). I use Firefox all day long on my desktop and phone. My account is synced on both. Is there a settings I'm not aware of?

Thanks for help.

Hi, I opened Mozilla after coming home from work today and had a few weird things happen. First things first, I was welcomed with a "Thank you for installing AdBlock" page. Which wouldn't be all that odd if I didn't use Ublock Origin instead. I removed the extension, ready to move on, but then I noticed all my bookmarks in the toolbar were gone! The ones saved to other bookmarks are still there, but the ones on my toolbar are deleted and not hidden. While I was investigating that, I found that my history looks weird? It's a bunch of pages on Nexus Mods that I visited a month ago or so but haven't visited recently.

Only my three devices, PC, phone, and Steam deck are logged in, but I'm worried my account has been compromised. I've changed my password and am trying to get two-factor authentication up.

This is version 119.0.1 on 64-Bit Windows 10. Due to an abrupt Windows update requiring restart, this browser should have restored the previous session, which it didn't. Edge was open to; and it did that with no problem. At the moment the box requiring restart showed, the screen froze with no access to Firefox settings. Still, it should have restored the previous session as Edge did.

I noticed that someone else had this question, but instead of answering it, it just got archived.

When browsing Youtube, the browser Back Button doesn't work. For example, if I start on the Youtube main page, then click on a video, it will show the video. But then, when I click the browser's "Back" navigation buttion, it does not take me back to the main page. The URL in the address bar will be the main page, but it will continue to display the video I just watched instead.

This only seems to happen on Youtube. It's been a problem for a while - possibly as much as 2 years or even more. And it doesn't happen every single time. However, it has been happening a lot more frequently lately.

It's almost as if Firefox just doesn't want to refresh.

I've tried clearing the cache. The problem persists. I've dried disabling all add-ons. It still happens. I've tried running it in troubleshooting mode. Still a problem.

I've tried to duplicate this in Microsoft Edge; it doesn't seem to happen there.

Hi Firefox We work in a government institution and we use Firefox because it is a unique, fast and safe program. We thank you for your efforts to develop the browser But we encountered a problem with the new update while printing the PDF files. It was showing us the option to print in portrait or landscape format, and when you updated version 14, this option no longer appeared. Where we deleted the new program, installed the older version, and stopped the update We trust you to solve the problem in the next update, and we ask you to give the matter importance

On all windows in Firefox, both normal and private, I get what looks like brushstrokes over the text. Generally they disappear when I move the cursor, but they also appear and disappear without mouse moves. I have the same extensions running on other PC's but don't get this happening, only on this newly-built PC. Using Windows 11 version 22H2, Firefox ESR 115.4.0 64-bit. In the sample the brushstroke shows about 80 % down the page. It disappeared after about 30 seconds, and other appeared later. While writing this, the same kind of thing was happening on this page. Extensions Ecosia and Ghostery.

I've been on the net since probably 1995, working in the computer industry. I buy a lot of items on the web, especially Ebay. I like to save the entire listing at the time I bought the item. Why, because listings change and it's frustrating. This way I have the full page in my Documents folder. Over the years, I've been running into problems with save Web Page Complete. More times then not it Fails, no reasons, just the little download icon goes red and it failed. That's how I know...I have read other support questions, but nothing other than a screen shot is recommended...Ugh. how can one screen shot save a page that scrolls in my browser for many pages...

So Why Do complete web pages fail to save?

Why are there no Descriptive Errors?

Is there something I can do to ensure I get this feature working again, reliably that is;-)

As always, I appreciate any help given:-)

When I compose a Twitter reply (desktop) text becomes garbled. If I hit 'Enter' message disappears. It I hit 'Shift' and Enter, cursor returns to beginning of sentence. Apostrophes don't render, at times.

It's as if a 1978 version of a word processor, you can type, but nothing else

Other posts, other websites work beautifully. v119.0, but has done this on every version, every configuration

Attached is me pasting ' issues with Twitter on Firefox ' into compose No idea

Thanks in advance

I get black and or white rectangles on web pages as I scroll or move the cursor. Some times they obscure what is on the page, sometimes a ghost of what is underneath shows through, sometimes they are like a layer between page components. I've attached a couple of screenshots to show some of the problems. I've reset Firefox but it made no difference. Any suggestions? Rhanks Tony

Every time I open Netflix in Firefox browser, to watch streaming movies, it won't show them but keeps taking me to a page asking me to log in again or pay for a Netflix account. (attached) I already have a Netflix account and can watch streaming movies with no problems on other browsers, but not using Firefox, which is my Default browser.
