Firefox-Hilfeforum

Hello,

I am a developer on an emergency intervention hotline for sexual assault.

Firefox is now throwing up psuedo-modal advertisements for it's VPN above pages. See attached screenshot for example.

It is absolutely IMPERATIVE that our visitors do not receive these new modal advertisements that Firefox is throwing at them. What can I do to prevent Firefox's new browser-hijacking advertisements from showing up on our hotline pages?

I experienced this on Twitter, and it 100% was not part of the dom. It also greyed out the tab bar, and prevented me from opening the menu with alt. I know how to make it not show up anymore on my machine, but how can I prevent it from appearing on visitors to my website, who are in some of the most vulnerable times of their life.

I been having problems with firefox using up most of my cpu while browsing some websites and it doesn't even load as fast as before. This has been happening for a few days now. Prior to this, firefox was fine and loading pretty quick, but these last few days have been painful.

Thinking that was a small bug, i restarted my computer. Before opening the firefox again, I opened up task manager to check how much resources will the browser be using. Before that usage would be normal and not even close to high, but opening firefox and waiting a few seconds to let the home window appear, the task manager showed that it was using all of it still.

I browsed some other help questions on this website and disabled "Use recommended performance settings", because that was one of the solutions on one of the relevant questions. But even that didn't do reduce resource usage either. Is there any way to fix this or will I have to suck it up and suffer with slow loading?

I have a few websites, among them glovoapp.com and work Kibana, that don't open properly in my regular Firefox session any more even though I tried to remove cookies related to those websites and anything else I could think of. They work fine in private window but it means I have to authenticate each time. What steps do I need to perform to completely clean a website settings from Firefox memory?

In case of Glovo (and several other websites) in regular Firefox session there's an error: Content Security Policy: The page's settings blocked the loading of a resource at inline ("script-src"). Same doesn't happen in private window.

In case of Kibana (and several other websites) in regular session Firefox somehow remembers old authentication - it doesn't ask for new credentials and doesn't send Sec-Fetch-User header (which results in Kibana throwing HTTP 405 Method Not Allowed). In private window the header is sent correctly.

I'm using Tridactyl so I tried to use the :sanitise glovoapp.com command which, in theory, should remove everything that can be removed with API calls as described on https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/browsingData/DataTypeSet - it's not enough.

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

Hi!

Let's start by saying that I love Firefox, that I use it as my primary browser everywhere and I love that is not based on chromium. However, for reasons to me unknown is missing a very important feature (natively at least): tab grouping. This feature is extremely simple to implement and in today life, where in most jobs (I'm a researcher) you have to deal with a tons of tabs opened in your browser, being able to effectively organize them is a must.

My question is: has Firefox the intention to implement (again) this feature? Will this happen soon?

I'm really trying my best to not switch to a competitor browser and I really want to support Firefox and hope that it gains more and more users. But for this to happen it really needs to be on par with time. How come every other popular browser has a very good tab grouping feature and Firefox doesn't?

Please, let me know if there's a chance to see this feature implemented in reasonable times. Sooner or later, you will probably have to do that reagardless.

Wish you the best, A.

Since yesterday whenever I put a video on youtube or any other site to full screen it does not goto fullscreen, the photo shows what I mean I have already tried doing this and it didn't work Go to about:config and make sure full-screen-api.enabled is true and reset the other full-screen-api settings to default while you are there.

Videos also do goto full screen on Chrome so it must be an issue with Firefix not my laptop

A month ago I started to have problem with twitch. After 5minutes or 2 hours- random times or random tabs, if I have opened more than 1, which is always the case. Some tabs or all, again it's random will give twitch 2000 error and refresh, closing tab,etc nothing will work, except closing WHOLE browser, not just tabs and this is not guaranteed that it will work.

I'm losing my mind with closing whole browser-windows-tabs on different monitors and then re-opening all of that again when I get 2000 error and I always do get it.

Did like 50 re-installs, it's always the same. I tried to go back to older version, but Firefox always want to create new profile saying I have old version installed and I DO NOT want that, I want everything as it is right customized,etc right now.

When I log in, refresh, or just open up the website, I'm met with an error message attached below. I use a HP Pavillion Laptop, Windows 11, and am on version 113.0.2 (64-bit). I've tried the following: - Make sure spotify is up to date - Restart my router - Make sure 'Widewine Content Decryption Module provided by Google Inc.' is enabled. - Allow Firefox to play DRM controlled content - Disabled my plugins - Tested this on other browsers (they work) - Made sure I'm not using a VPN. Oddly enough, Spotify's web player seems to function alright in Private mode and the app is fine too. I will try any all solutions presented, please.

I recently got help (thank you, Cor-El!!) and was able to put Firefox into compact mode. It's still not enough. Is there anyway to make even compact mode smaller? After websites add their own headers and all, it now leaves me about 2 inches of working space; it's better than one inch but isn't enough to see things.

I've been trying to keep going back to version 99 (darker attached screenshot in blues) but it isn't being allowed. The other screenshot (lighter, in oranges and pinks) is the current version in compact mode. It's a bit better, but still is not good.

Is there any way I can change the height of the headers myself? Or can I ask someone else to do it? I'd like it about half to 2/3 the size it is now, even in compact mode. Can I do that? If so, how?

Or, can I switch things around so the headers are at the side of the screen? This is a standard 15" diagonal screen laptop currently running Windows 10.

I will be moving all of my data to a new laptop and want to know if I need to have both my personal Firefox profile and the "default-release" profile backed up. The "default" one is over 3GB and has over 20k files in it, and my personal one is only 113 MB with 1300 files — and my thumb drive needs all the extra space it can get. (Why would the "default-release" profile be so much larger than my personal one?)

The old laptop runs on Windows and the new one will have the Linux OS. Will that make a difference in using a backed up Firefox profile? I mean, will the data still work in the new OS?

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

So I have installed 1password to my browser but i need the add on to show in my toolbar but when i click customise toolbar, i cant find the add-ons option. Please help

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.

Suddenly (last day or so) the timestamps on Facebook posts are missing (except on the first on the timeline). The data is there, you can hover over the location where the timestamp should be and the date and time will pop up. This still works as usual on Chrome, so I don't think it is a Facebook issue. Thanks, Robert

With the latest update, I am unable to use the "Tools" button on Google search (to do things like results from past week, month, etc.). I have disabled all extensions and restarted the browser to no avail. What's odd is, I am able to use the Tools in a Private Firefox page with or without extensions enabled. But on my normal browser, the button doesn't work regardless.

Perhaps it was timing and the issue just started occurring when the update happened but I'm unsure how to solve it.

Thanks.

I am on a unstable internet connection and while trying to download a large file it gets often interrupted. By default Firefox deletes the .part file and I am forced to again download from zero. Is there a config that I could change so Firefox keeps .part files so I could continue resuming the interrupted download?

Hello everyone.

I've been using Firefox for quite a few years now and I'm used to keep my pinned tabs open after closing and then opening a Firefox windows.

Yesterday I noticed that after closing the navigator with the "X" in the tool bar menu, as I usually do, the pinned tabs are not "recovered" when opening again.

This happened randomly without configuration changes involved and drivers/firefox are updated to the last version available.

Moreover, I've tested the same in my notebook and it works just fine, as it keeps the tabs open when a new window is open.

Is there any troubleshooting for this or do you have any idea what could have caused this to happen?

Let me know if you need any additional info. Thanks in advance!
