Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

Some files that are visible in my PC's directory are not visible to Firefox to upload to attach to a Google g-mail, even though they are visible and uploadable to g-mail in Chrome. I created 4 similar (all pdf) files (printed from Adobe), but only 2 are visible to Firefox!!??

This has happened before. I try re-creating the invisible files, but have no success.

Unless I can fix this issue, I'll have to stop using Firefox.

I am running into a 414 error that prevents me from accessing account information in Kindle Direct Publishing, has anyone else run into this problem? I log in and get to the home page of KDP ok, clicking on Account opens dialogue box to log in again, and I get 414 error, which KDP help AI says is browser related. I've tried using incognito, turning off VPN, there are no extensions turned on, going directly to the Account Settings link gives same error. I tried using another browser (Safari) and get same error.

Firefox 155.0.1

Thanks for any other suggestions!

I'm experiencing continuous screen blackouts or glitches. These are unaffected by the site I'm on and only occur for Firefox browser. When I switch a tab or click a button the browser blacks out and becomes unresponsive then comes back on after a few seconds. This happens repeatedly. Clearing the cache, running a repair, and uninstalling / reinstalling the app have had no affect on it.

this exact question has been asked last year, none of the suggestions work: I am running Firefox 154.01 on Winux I have lost sound on Firefox. I have opened the same sites in Chromium and the sound is working fine. It's only in Firefox. I have tried several sites including , YouTube, and radio programs, no sound from Firefox. All of a sudden the sound disappeared. The speakers is turned on the volume is up, just not a sound from Firefox. What to do? Right now I had to switch over to Chromium

After today's Firefox update (7/30/26), I can't activate DuckDuckGo search. When I type a search in the URL bar, if i select a bookmarked URL, it will launch the bookmarked URL. However, if I select a search query (ex. "sonicare toothbrush" in attached pic #1), it won't allow me to press enter to launch a search.

Under Settings, when I click on "Activate" DuckDuckGo search (attached pic #2), nothing happens.

Здравствуйте, подскажите, можно ли войти под одним профилем но иметь разную панель закладок? Например я вошел под профилем для поиска информации в браузере и есть панель закладок для браузера, которыми пользуюсь. Также я скачал Firefox Developer Edition также вошел под тем же профилем, но хочу чтобы панель вкладок была своя, и не пересекалась с обычным Firefox. Можно ли так сделать? или нужно создавать вторую учетную запись для разработки в Firefox Developer Edition

Running 154.0.1 on MacOS 26.6.1. Sometimes firefox stops working and I think I'm having an internet issue. No page able to load, not even a google search. I see the cache is full at 1gb and I clear cache for the last hour. Browser starts working again. To me, the problem doesn't seem like not enough cache capacity but the browser refusing to evict old, stale cache. How do I fix this other than manually clearing the cache? This seems like a bug that should be fixed.

title sums it up mostly. I've entered troubleshooting mode; no discernible difference. When I switch profiles the issue is resolved even with the same YouTube account. Tried clearing the cache, nothing. Most recent version of Firefox, windows 11.
