Trying to not just edit a PDF in Firefox on Linux but actually edit the document using its Dynamic-XFA format elements of that PDF. XFA is an Adobe proprietary format that they depreciated several years ago but it still works in Adobe Acrobat Free. (I use a Windows guest VM for this as a workaround for now but I'd rather not since it takes extra resources and time). Elements can be filled in FF and some menu drop downs work in FF but other dynamic XFA element buttons don't respond like the one I attached.

In Acrobat the "X" and "Add Contact" buttons will add or remove some elements to the document.

Can this be done in FF desktop?

Version 151.0.1 (64 bit) on desktop PC.

In about:config I know there are a lot of options to modify under the search term "pdfjs" but I don't know what element would allow this to possibly work if its supported.

I wish I had other better options but government documents are what they are.

Firefox 151.0.1 64 bit for Arch Linux I am trying to create a desktop app from a website - the ai is saying if there is no + sign in the url box then try More Tools -> Create Shortcut but there is no Create shortcut there. So how to create a desktop app from a website?

When I click to fill in a Credit Card field to pay for something, my correct card info appears momentarily, but then disappears. To execute a payment, I am forced to manually fill in all required information. I made sure the "save autofill" box was properly checked in the Settings, and it was. Names, addressed, etc. are all filled in properly; only credit card info is not.

I access google drive through Mozilla Firefox and also zip file or other file download but since 1 to 2 weeks i faced issue to download files especially js file.How can I solve this?

I use Firefox with DuckDuckGo on Ubuntu 24.04, Gnome desktop. My Firefox browser window regularly freezes but can be unfrozen by simply repositioning the window. This is really annoying.

I also use Chromium on the same system and there are no issues.

Any ideas?

Hello,

I have noticed behavior in Firefox that seems inconsistent with my expectations of Private Browsing.

When I open a Private Browsing window and begin typing in the address bar/search bar, Firefox still shows my previously searched queries as suggestions. I am not signed in to any Firefox account, Google account, or other search engine account, so these suggestions appear to be coming from Firefox's locally stored search history.

I understand that Private Browsing prevents new history from being saved. However, I expected Private Browsing to also prevent existing search history from being displayed while using a private window.

Currently, I can disable address bar suggestions entirely, but that removes them from normal browsing as well. What I would like is:

• Search history suggestions available in normal browsing windows.
• Search history suggestions hidden in Private Browsing windows.
• Existing search history not exposed when using Private Browsing.

Is this current behavior intentional? If so, is there a setting, hidden preference, extension, or planned feature that allows Private Browsing windows to suppress history-based search suggestions while preserving them in regular browsing sessions?

For reference:

• Firefox version: 151.0.2 (64-bit)
• Operating system: Arch Linux

Thank you.

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Firefox version 145.0 in Linux Ubuntu 22.04.5 LTS. When I open Firefox all tabs from previous session are gone. On "Startup" I have checked "Open previous windows and tabs". Which worked before but not now. It is very frustrating. How do I fix? The Profile Manager opens the settings and "Open previous windows and tabs" is checked. Checking "ask before closing multiple tabs" doesn't help.

After the last Linux upgrade to 36.0.2 the password or user name hot links only work once. The first time the link is gray and will activate. The second time I try and use this feature the link is not gray and will not activate.

Every time this happens I have to close Firefox and reopen it. Then I get one more shot at auto loading a password before it stops working.

Not sure if this is a Linux or Firefox issue, but here goes. In the past when uploading pictures for instance in Gmail I got a menu showing places EG pictures, video's etc. Example - home - pictures- cats - black cats - list of jpg's, click attach. When attaching another pic from the same folder etc it used to default to the same folder location with the list of jpg's.

With the last few FF updates that isn't the case any more, when next attaching a pic file I now have to start again from scratch EG home, pics, cats, black cats instead of click attach straight to list of jpg's in back cats.

Is there anyway I can configure FF back to the old setting please?

Firefox automatically creates an empty "Downloads" folder in my home directory that I don't need. My browser settings specify a different file save path. How can I stop this? I'm using Firefox 151.0.4 and Rosa Linux 13.2 (Fedora clone).

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Hello!

 Since some days I have the problem that all files I download from outlook are accompanied by a preceding UTF-8 in the file name. This is not the case for e.g. google chrome. Can I fix this problem by myself, or is it a general problem of firefox 128.9esr (64-bit)?

Firefox lived on my computer for three days. On May 30th I installed the latest version of Firefox Developer Edition. Today when I launched my browser I saw a page notifying me that my version of Firefox is the latest [152.0b6 (64-bit)]. All installed extensions disappeared, the connected profile was deleted, the .mozilla/firefox directory contained only the newly created profile... No history, no bookmarks... No crash reports...

What happened? Now I'm afraid to sync the browser with my phone, in case it clears all my passwords.

My current version of Firefox is 149.0 (64 bit) Mozilla Firefox for Arch Linux Arch Linux - 1.0 I am running this on two computers, a laptop and a desktop, both running Arch Linux, currently at 6.19.10. I use the laptop much more, and recently noticed that I cannot upload or download files with Firefox. No file selection window opens and the request is simply ignored. Nothing appears in my Downloads folder. Meanwhile, I also noticed that this function works just fine on the desktop computer. I don't remember making any settings changes. I do have popups generally disabled but can enable them for certain sites. In any case, I have tried enabling popups and redirects completely with no change. I figure there must be something different about the settings on these two Firefox installations, but what? What can you tell me? Or ask me? Thanks.

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.
