I-Firefox Community Forum

When I download Firefox initially I am able to set the home page the way I want with the shortcuts I use. After a few weeks the shortcuts disappear and the only way to get them back is to delete Firefox and reinstall. I am also not able to save bookmarks anymore. This has the same resolution methods.

This has happened 3 times already.

My mail checker extension isn't working right in Firefox. Extension Link I was able to find an error using Developer Options but I don't know if the error is even related to the extension or if it is even useful. If anyone would help me, I would be very grateful.

Hi Fresh reinstall WIn10Pro home office pc -- want to ensure OS (WIn10pro x64) doesn't alter behind the scenes.

Want to prevent MScopilot or other rogue AI is not hiding changes unclear/unknown to user. Pc Admins and also PC std users

Have FF v140 syncing to a Msoutlook userid and have donated under that id. The donwloaded install was done via a private window as Edge had to be used.

New installs of everything. Full virus scans etc. latest updates. But still seems like MS trying to prevent using FF unaltered.

Is it best to set up a profile and then disconnect sync; then reset FF periodically and turn sync back on? Some IT people said they've done that for a while.

Are local windows users not supposed to be able to save FF settings?

Are we inviting in MS by syncing and/or donating to Mozilla / Firefox with outlook.com addresses?

Thanks.

After updating Firefox yesterday, when I use the search bar, switching between my custom search engines can only be done via clicking on a drop down menu at the left end of the search bar and selecting one with the mouse cursor. Previously, I could select my preferred search engine by using the up or down keys to cycle through them while typing a search, then hitting enter when the one I wanted was highlighted. Having to switch from keyboard to mousepad while typing a search is really annoying, I found the old way much more convenient. Is there a way to revert this, and put the search engines back at the bottom of the search suggestions, where I can access them with arrow keys?

Also, when I search now, the search stays in the search bar instead of changing to a URL, and I have to click a little internet globe icon at the right end of the bar for it to show the URL. This is also kind of annoying. Is there a way to turn this off, and just set it to show the URL every time?

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

Firefox 139.0.4. version is also not good! Uploading videos to Youtube does not work with it! It does not move from zero percent! As I wrote earlier, the problem started with version 138.0.4. and is still ongoing! Uploading videos works with other browsers! I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!

I own a website that has chat rooms for each of my advisors. As of 2 days ago they are all having issues. I have them login with Firefox but now asking them to use Google Chrome...............low and behold it works

Whats the issue as i believe it started with the latest Firefox update

Thanks so much

Sir/ Madam,

    It is delight to use and experience with Firefox Mozilla browser. I request to  make Firefox Mozilla as main.

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

Since the last update Firefox sends the processor load through the roof. Both on desktop and on Android. For the first time since like version 7 I'm a bit disappointed.

What's up with this?

Dear Firefox Team,

I’ve been a loyal Firefox user for years, and I generally love your browser. However, I recently experienced a serious issue due to how Firefox handles saved sessions, cookies, and multiple logged-in accounts.

I had two Gmail accounts saved in Firefox, both of which were at some point used to access Fiverr accounts — one active, and one previously disabled. During a session where I was logged into my active Fiverr account, my internet went down temporarily. When I refreshed Fiverr after the connection came back, Firefox reloaded a session that appeared to be linked to the disabled Fiverr account — even though I never intentionally accessed it.

As a result, Fiverr’s automated system flagged my active account for being "connected" to a banned one. This has had a direct negative impact on my freelancing career — my account was permanently flagged, and I lost access to valuable clients and my work history.

I understand that session management and cookie handling are standard browser features, but I want to highlight how important session isolation and protection from unintended auto-logins are, especially for freelancers and remote workers using platforms like Fiverr, Upwork, and others.

Please consider offering better controls or clearer separation between accounts (e.g., warning before auto-loading saved sessions, stronger isolation per Gmail/Fiverr session, or more powerful multi-account browsing containers by default).

This small technical behavior has led to a major professional loss.

Thank you for your work on this browser, and I hope you’ll take this feedback seriously to help prevent this from affecting others in the future.

Sincerely, A frustrated (but still hopeful) Firefox user

HI I cannot add an additional tab on top to open. I usually had no problem I need to open 6 to 8 tabs a day for work. Did firefox add a new version? every time I open an additional tab it closes the one I have open.

I don't know what happened is this a new version opened in fire fox.

Thank Linda

After updating to newest Firefox 140.0.2 (64-bit) does all PDF attachment stop working it doesn't offer to save or open them as it used to, we tried sending a Doc document to the email and it will download them and open them so it is only PDF files.

I tried new profile with blank slate on her PC.

OS: Windows 11 Have Bit defender security and Malwarebytes

I also tried on my PC logging into the work email as neither me or wife use Apple and same problem PDF attachments will not open or work.

I didn't create a new blank profile on my PC.

My PC: Windows 10 Enterprise Have same Bit Defender security and Malwarebytes

It worked in 139.0.4 for her, but downgrading is not a option as if I read the downgrade page right it will make a new profile making her loose the profile she is using now.

Do anyone have any ideas why after the update does Firefox now not open PDF Attachments, we tried Edge and it work fine there, if she forward from the work email to her private which is a gmail account she can open the PDF files, but that is not a good way of doing things or acceptable as it is work emails sent from companies her boss work with, he is a car mechanic with his own mechanic business.

Please tell me what details you need from me to help her find out why it stopped working or anything else I can try.

The Work place is just her and her boss plus 1 employee so I help with the IT on the work computer so I need to find out why this update stopped PDF attachments from working.
