i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

Firefox FREQUENTLY totally removes added applications attached and it totally screw up my ability to access anything when you remove my Bitdefender application from access then I have to again EXPLORE added applicaitons!!

Over the past few weeks, my typing is continually being interrupted. It did this a few years back, but this is getting very annoying and I am soon to switch browsers if not fixed. BTW on any machine using Firefox, this is happening

I use multiple Firefox profiles and create separate desktop shortcuts for each profile using Firefox’s built-in profile shortcut option. I then pin each profile shortcut to the Windows taskbar so I can launch them independently.

The issue is that when I click one of the pinned profile icons, Firefox opens a new separate taskbar group/icon instead of attaching the window to the already pinned taskbar item for that specific profile.

For example:

• I pin Profile A and Profile B separately to the taskbar.
• When Profile A is already open and I click its pinned icon again, Windows creates another Firefox taskbar button/group instead of reusing the existing pinned Profile A button.
• Google Chrome profiles do not behave this way on Windows — each profile stays grouped with its own pinned taskbar icon as expected.

Is this a known limitation/bug with Firefox profiles on Windows taskbar integration, or is there a way to make Firefox profile shortcuts behave like Chrome profile shortcuts?

I can't log into chase.com from Firefox, which I've been doing for years. I get an outage message. But down detector shows nothing. It went on for days so I tried Microsoft Edge with Bing and it works. Is there some Firefox setting I need to change?

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!

EDIT: I found this, may is something similar: https://connect.mozilla.org/t5/ideas/send-tabs-log/idi-p/15640

This issue just started today.

I was attempting to watch a video on patreon, and normally I pop out the video so it is larger. This normally has no issues.

But today when I hit the button to pop it out, Firefox crashed.

Firefox then updated, so I thought maybe it was just because it needed to update.

I attempted this two more times with the same result. 

The first like I normally do where I start the video and then click the "pop out" button. Then the second time with the video paused. The minute I click the pop out option Firefox just crashes closed either way.

When I click on option/link for "Print using the system dialog box", the print preview no longer works. Instead I see message "This app doesn't support print preview" in preview pane.

I was trying to do something with my bookmarks yesterday and I must have pushed the wrong icon. Firefox then became unavailable. I'm 88 years old and not fully at home with computer language. I tried Chrome, but it's not available like Firefox.

Using Firefox on Windows 10 Pro & 11.

Beginning in v 150.0, when a media playback occurs, the audio volume in the player gets set to its maximum level. This is true for X.com media and for YouTube videos.

For YouTube it only happens for the first video played in a new tab; subsequent videos in the same tab 'remember' the volume setting from the prior video. In X.com, every media player invoked reverts to the maximum audio level.

In v 149.x and earlier, the media player maintained the audio level from its prior invocation.

Is there a way to have the media player 'remember' its previous audio setting when it gets invoked?

Steps that remove my pinned tabs from Firefox:

Open pinned web app from taskbar. Open regular Firefox browser.

Any pinned tabs that were in the browser before opening the web app are lost.

Is this already reported? I can't imagine this is intended behavior.

Went to VRBO website to look at a reservation and the website, which showed me as signed in, showed nothing of the reservation. Said I had no reservation,, no history of saved searches. When I used Microsoft Edge, all my previous reservations, searches etc. were accessible. I cleared my Firefox cookies, etc. still had the same problem

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?
