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.

I need to stop Firefox from reordering my tabs. Apparently it puts the last used one at the rightmost place. I DO NOT WANT OR NEED THIS.

How can I stop this behavior?

thanks

I am just writing to tell you that you can go stick your latest "new and improved" feature (note extreme sarcasm) in AI chatbots where the Sun don't shine.

Someone tell me is Mozilla trying to destroy Firefox?

Are they trying to get people to move to Edge, Chrome, Safari or Opera?

If they are they are going the right way about it!

I am getting sick to the back teeth of Mozilla forcing their crap down our throats.

I have lost count the number of times I have had to go into about:config to turn off the latest crap FX has forced down our throats over the years.

None of us asked for AI Chatbots which is one of the worst ideas ever invented.

I already had to delete Microsoft CoPilot from my PC last September now I had to do it with FX.

Everybody do this and it works:

Goto address bar and type in about:config, goto the search bar and type chat and where it says browser.ml.chat.enabled change from true to false and you will be rid of those garbage chatbots.

I have done that for every forced you you feature FX has added over the years like Pockets and Screengrab and all the other garbage they have added over the years.

When I started using Firefox today, I found that I can't always click to open links. Often right-clicking to open in a new tab works, but I've run into at least one case so far that doesn't.

Examples:

1. the link to go to the log in page for a medical practitioner - right clicking to open in a new tab didn't work, I was able to open it in a private window

2. a "confirm subscription" link in an email - I right-clicked to open it in a new tab

3. I'm logged out of my password manager (Proton Pass) or at any rate when I click on the Proton Pass icon in the toolbar nothing happens - normally it logs in, or if already logged in, then clicking the icon opens the vault.

My computer installed a Windows update yesterday. I haven't futzed with any settings in Firefox or my usual security & privacy extensions recently. Not sure how to start troubleshooting this - aside from turning all of my extensions off just to be sure one of them isn't causing the problem.

Hi, following a recent update installation I have not been able to log onto BT Webmail to deal with my emails etc, it seems to go into a kind of loop and keeps showing a log in page quickly, then it disappears and reappears straight away again, does anyone have any idea why this is happening, I have checked the version and it's 137.0.1

as in the title, my bookmark bar content becomes invisible the space of the bar is still there but its empty after i resume from hibernation , i havent witnessed the particular moment it happens, im simply confronted with that problem ever since i updated to this build

have to restart the browser for the bar to be populated again with my saved bookmarks.

The "other bookmarks" button and the arrow left of it are unaffected by this

I’ve added an iFrame to my website, but it’s not displaying in Firefox—although it works fine in other browsers. Here’s the link to the page: https://hoploninfosec.com/ibm-flashsystem-5300/ Can anyone help me figure out why it's not showing up in Firefox and how to fix it?

Use to be able to use the Ctrl-D to save bookmarks, but for a while this doesn't work any longer. The work around is to open manage bookmarks, add a bookmark, it works, but gets tedious. Read the article on cannot add bookmarks.

There were multiple copies of places.sqlite with variations and two with the current date. Selected one of the two with the current date, opened to properties, the read-only was not checked already.

Found xulstore.json and deleted file.

Opened Firefox, all the bookmarks were gone, imported bookmarks, passwords, etc. from Chrome which I was also using.

After that, Ctrl-D to save bookmark still wouldn't work. Now I will try deleting Firefox and residual files in hopes of a fresh clean copy of Firefox that would work as intended.

I found social media sites wouldn't work under standard or strict setting: x.com, bsky.app, mastodon.social, linkedin.com. Facebook does work under strict setting.

I have another laptop, and no such issue with Firefox. I really liked and use firefox for many years. Recently other issues had been with cloudnet unable to verify caused me to switch to Chrome, but I'm hoping this next step of re-installating firefox would fix the issue I'm currently having.

I updated FireFox to Firefox 137.0.1 (20250407111027) from Firefox 136.0.4 (20250326231000). Then, any time I would open ChatGPT, the text input box has been squished to ~30% of it's size which is resulting in formatting errors when copy pasting code or text from ChatGPT. I have the Zoom set to default settings, cleared cookies, and restarted firefox but the problem still persists. Is anyone else having a similar issue?

Проблема в том, что в мозиле, в отличии от хрома, у меня на экране окон не отображается сразу все окна если их открыто много, их нужно пролистывать срелочками вправло или влево, в хроме видно сразу все окошки даже если их куча, они просто сужаются, как сделать так же в мозиле?

I'm working onoptimizing a web application optimizing a web application and noticing some performance lags (e.g., slow page load and laggy interactions) specifically in Firefox.

I’ve used Chrome DevTools for performance profiling before, but I’m not as familiar with Firefox’s tools. I see there's a Performance tab, but I’m not sure how to interpret the flame chart, event markers, or how to pinpoint what's causing the slowness.

Can someone guide me through the process of debugging performance issues debugging performance issues in Firefox Developer Tools? Specifically:

How to profile JavaScript execution?

How to identify slow rendering or layout shifts?

Any tips for using the memory and network panels effectively?

I’m using Firefox version XX.X on [OS], and this is a React-based app.

Any tips, resources, or walkthroughs would be appreciated!
