You have suddenly blocked my access to BlueSky. Please restore it. Now. Blocking this on the eve of the new President's installation makes me question your motivation.

Have been "printing" web pages to PDF for ages. All of a sudden one site creates a PDF output with 0-bytes. i.e. it's empty. Other sites I use still work normally.

Firefox 134.0.2 (64-bit) on iMac

Lost ability to drag and drop.

FF 134.0.1 Apple M1 Max Macbook Sequoia 15.0.1

GIVEN I download a file WHEN I drag from "recent downloads" in toolbar to g.drive THEN nothing is moved, nothing is under cursor

expected: file drops into g.drive from downloads

GIVEN I have a window up with many tabs WHEN I select a tab and pull it to make a new window THEN nothing is under cursor, and I don't get a new window

expected: new window created from open tab

Hello, when I download PDFs and open them in the Firefox browser, only the text blocks or image blocks have a white background. The rest of the page then has a dark background. I have already checked things like dark mode etc. Do you have any suggestions for a solution?

By using Process Explorer or Process Hacker or maybe task manager, I hope you can also verify that Firefox consumes a few GDI handles per open tab. Windows has a global limit and a per process limit of 10000. GDI objects are used for windows, for the file save dialog and also for user interface elements like buttons or lists. However many applications like Firefox draw everything themself like XUL etc. But still, Firefox consumes 3 handles for me (verified on another computer) per open tab.

If you have a lot of tabs open (for reasons not to be discussed in this topic) this can be problematic. If it reaches 10000 windows will not create more. Sometimes firefox hangs, but often Fullscreen (e.g. youtube videos) will not work and the gui will disappear. Also the context menu will not open and the save dialog cannot work and is hidden.

Am I the first to report this? I did not find anything. Can this be fixed? Can I post this to bugzilla?

Can anyone confirm this? The latest version does not fix it.

Hello,

I am experiencing discoloration on the top left corner of my firefox browser theme when I am in "full screen view". The discoloration disappears when I exit from full screen mode to "window view". This discoloration is happening on every theme I enable. I have attached two pictures to show what I am seeing between the full screen view and window view.

I am running Windows 11 and have a 32" curved monitor. I searched for solutions such as disabling hardware acceleration, but nothing seems to be working.

Any help would be really appreciated!

Thank you!

Recently when I try to download a file Firefox seems to give it a random amount of time before it attempts to open the file. For small files this isn't a problem, as it always seems to give at least a few seconds, but larger files get cut off. This leaves the file corrupted/incomplete.

I have no idea why is started doing this. Just one day it started opening everything I downloaded, be it PDF, image etc when complete. I turned this off and it has stopped for things that download properly, but it's still doing this 'cut off' attempt to open.

Any help would be appreciated, thanks,

Every time I launch a fresh copy of Firefox all my saved accounts ect are gone. Now I know they aren't gone because the profiles.json files is still there. What has happened is firefox has taken the cookies.sqlite and added .bak on the end.

I've reinstalled firefox, tripple checked my settings and clearing stored data on browser close. What am I missing to stop firefox from doing this?

Hello!

I am reaching out regarding an issue I am having lately. Recently a great number of sites has been showing me an error regarding an embedded site and blocking me completely from it's content.

I've read on many forums and searched the brower console and it seems like firefox is having an issue with X-Frame-Options being set to "sameorigin". It gives me a lot of trouble and is blocking me out of a lot of media.

I love security measures Mozilla has implemented over the years but I do not feel comfortable when software I use won't let me toggle less important safety features On/Off or at least whitelist sites I know are safe.

Speaking bluntly, it's ridiculous that I have to try 10 different websites with the content I want to watch, just to find one that has a built-in player, instead of an embedded one. It also seems to be spotty with what it blocks and what it doesn't block as some sites with an embedded player work with no issues.

I couldn't find any way to turn it off that won't possibly affect other security measures, or won't require me to go into brower console every time I want to access media.

Please instruct me how to fix this issue and consider making changes regarding it.

Thank you in advance :)

How do I prevent MSN from opening Firefox? I am not interested in just blocking the site or a page, I want to block Microsoft from opening software that doesn't even belong to them.

Hello to you up there ! I have Windows 11 - 23H2 up to date ! since 21/1/2025 each time I start Firefox (up to date 134.02 - 64 bits) I get a warning from Malwarebytes Browser Guard that blocks a outgoing request coming from Firefox via port 443 to the IP 82.221.136.1 ( = welcometothemachine.co …. what is that ?? analytics ? AI  ??) .... I am asking myself why is Firefox trying to go to that IP because I never did ask for something like that and how to delete the whole request every time now .... (CCleaner does nothing when used) ... bizarre bizarre behaviour yes ! Who can answer me. Can you please also answer me on geomar@scarlet.be because I would not like to miss the answer ? Thanks.
