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.

On some sites the popup to change cookie settings is not opening properly I have tried disabling all extensions or browser guards like malwarebytes but stiil not working. Everything works using a different browser.

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.

When I try to go to Google's website, I get this message:

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Error Code: PR_CONNECT_RESET_ERROR

The same thing happens with YouTube TV. My Bitdefender also flagged it as a suspicious page.

One instance does not have bookmarks and passwords. The machine keeps switching between instances for Default. Machine is Ideapad 1i Windows, 11 64bit. Both Versions of of Firefox Appear to be 155.0.

On my new dell laptop, Firefox seems to run well. however, when I select one of my regular bookmarks from the dropdown, it ignores the choice and chooses a link (e.g. a news story) from the page I'm currently on, one directly under the bookmark I've chosen. If I choose the bookmark link again it operates correctly.

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.

I hopped over to the ideas page because I had a couple suggestions, and found I was not alone because lo and behold someone else had the same ideas. So I decided to agree by hitting the kudos button, but imagine my surprise when instead of adding to the number of users who supported the idea, this feature only seemed to reload the page for me!

This has happened on two different video sites already. While watching a video, it will go extremely dark and happens randomly. I also get a weird blank window frame sporadically. I've unjustly been reporting this to one of the video sites until I noticed the same thing on Youtube.

I don't know when it exactly happend but arround 3 months ago my Firefox is on the verge of dying anytime i open a new TAB it takes about a min to be funktional again which is a pain!

before that time Firefox was quick never hade these problems before! A friend of mine has the exact same problem as i do.

honestly will not read the awnser on this post but i just want to make sure its on the Board

Tab groups disappear when window closes, another group adds all the closed group's tabs. This is stupid. When I restart Firefox, or it decides to close, or restart, or whatever, if I have more than one tab group in the window, all the following groups disappear. And then they are added to the remaining group. So then I need to remove them from that group and put them back in the original . This is ridiculous. Why don't all groups remain in the same window with all their tabs intact and not redistributed?

Windows 11 , Version 155.0.1 (64-bit)

When listening to live internet radio, after varying minutes, browser stops and I have to refresh and re-establish link. Does not appear to be related to sleep or desktop display issues. Any suggestions how to correct?

I am a loyal firefox user and have used it for years. Security and features are great. I use Google docs constantly throughout the workday on my Mac and I am constantly having problems with Firefox. Google docs that I work in are constantly re-loading, incompletely downloading, going offline. I typically have 5-10 docs across the platform open at a time, and the problems are preventing me from working effectively. I have tried searching help forums and done the fixes suggested (repeatedly clearing cookies and cache, turning off protections, etc). Nothing works. Any ideas before I switch the Chrome (yuck)?

Any time I have another application open and I pause a YouTube video or music everything on my computer mutes. I tried to disable hardware media keys in config but that just mutes my entire browser
