Hi, Firefox sync not work with changed useragent. I have changed useragent in (about:config): general.useragent.override Our company identify and block Firefox globaly in proxy servers. Why? I don't know (maybee dificult globaly Firefox updating for non admin user).

I open Firefox sync and try login there, but I see only progress (wheel).

I have tried to upload files in several websites and the "upload" button isn't working. I tried in Safari and I'm not having this issue. It's an issue keeping me from working. Does anyone know how to fix it?

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

After updating to Firefox 103, everything in the browser including web pages, are way too big. Oversized. What the heck happened? Why do they do this? On the tool bar with the address field, on the right, I have a zoom icon, etc., and they're all much bigger!

I could adjust zoom, but this is not right. It's all messed up!

Yes I went into Customize Tool bar - Density - and it was already set to "compact - not supported"

I went into about: config - browser.display.os-zoom-behavior - changed to zero. Nothing happened.

I went into the windows settings - display - set to 125% which it always was. Changing to 100% didn't do anything. Went into display - Make display bigger - and it's 160, where I always had it.

Not happening in Chrome or Windows. So it's Firefox.

I've downloaded a couple of add-ons this week that did not do what they claim to do, so I wanted to leave reviews so other users won't waste their time. Except when i got to do so, i am surprised to see that therte is no clear way to write a review for an add-on. I am logged into the add-ons page, i can view the previous reviews for the add-on, but nowhere does it inticate how I can leave a review. Google led me to the Mozilla add-ons wiki which states "You can complete most of the review using the reviewer tools at addons.mozilla.org" except there is no indication to where one can locate these "reviewer tools." Seems a bit funny to me that Mozilla would choose to hide the functionality and make it so difficult to use.

Any help is appreciated.

I use Mendeley Reference manager in Firefox. It used to work OK. Now I get a message "Firefox blocks extensions running on PDF files". This is just what Mendeley does. How do I get Firefox to allow this to happen again?

Currently @ Ver. 102.0.1 Problem remains. Since the update to 102.0 my Win10 PC has problems with the page update. When the scroll slider gets near the bottom the page, new images begin to load. This reload results in 3-15+ newly loaded Fb posts scrolling past so fast as to be invisible. I have to keep my cursor on the scroll slider and, when the loading begins, start scrolling up if I want to have any chance to easily find the last post I was reading. I have seen this behavior, grossly exaggerated, when I was viewing a video. The reload caused the viewing to pause and upwards of 15 newly loaded posts scrolled past in this rapid manner. My work requires that I am able to view pages of Facebook posts and this is now massively time-consuming and intolerable. I may have to change browsers in spite of my reluctance to do so.

Since the most current Firefox update in June 2022, when in Yahoo Mail and downloading an attachment, as the download complete, the Yahoo Mail tab is automatically closing, requiring I to go to 'History', then 'Recently Closed' tabs to re-open it. This happens Every.Single.Time I download photos and scanned docs from email. Again, this has never happened before - only with the recent Firefox update. I have 2021 a MacBook Pro.

Random videos will not load following 100.0.2 install.

These symptoms started @ May 21. (See attached file "Recently installed")

This problem is 100% reproducible at: https://www.reddit.com/r/CatastrophicFailure/

Lenovo Thinkpad x140e Windows 7 (all updates installed) Mozilla 100.2.8174

Scrolling down the Reddit page, videos will auto-play when exposed, and stop when scrolled past.

A video not loading/playing will occur on different posts/videos, but will ALWAYS occur. Once this occurs some previously exposed / played videos, when scrolling up, will play when exposed again, and some will not.

This will also randomly occur on Youtube (also observed on Twitter a few times) when multiple tabs are open. Sometimes closing other open tabs corrects the problem. Other times closing Firefox and relaunching is required and is 100% effective.

I have additional diag data / Inspector log files and page source if needed.

Thank you in advance for your help and consideration. - LudditePro

I've noticed there is a "verified by Amazon" icon in my address bar next to the FF shield. How did it get there, can, or should, I remove it and how. I don't trust anything Amazon does, so if possible I would like it to be gone.

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

When I create a file to print in Firefox ( in this case from Etsy ) the preview looks ok but when the file is printed or saved as a PDF then the text parts of the file are ok ... but the images are much too large.

You can see this on the attached images ... how it should look and how its coming out!?

Any help gratefully received :-)

After the most recent update, v.103, any image-based PDF that I print out is extremely oversized despite appearing correctly in the print preview window. I have tested other browsers and did not have this issue. I have also reset my Firefox print preferences and my printers/drivers to ensure it's not that either. Does anyone know what could be causing this, besides an issue with the new update?

I am sending push notifications using Firebase Cloud Messaging but I am not able to receive it in Firefox. But, when I send same push notifications to Google Chrome or even MS Edge, the notifications shows up smoothly. I checked everything, serviceWorker is registered for my website correctly, but still push notifications do not show up in firefox.
