Firefox Support Forum

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

I can login from other web browsers, but not Firefox. What's going on?

When I try to login as I have always dine in the past, this is what comes up: https://outlook.live.com/mail/0/

But then absolutely nothing happens. Please advise.

For some time now, I've been experiencing the following issues with PiP:

• The floating window opens in a random (and annoying) place and does not place itself automatically on the lower right corner as it used to (where I always move it, so it has no memory as it used to)
• It's impossible to keep the "always on top" mode on by default, and I have to do it every single time
• When I toggle windows, the PiP window is always the next one, even when it was not the one I switched from, and I have to always toggle twice for switching between two windows when I have a 3rd PiP window
• When I change language using the keyboard shortcut, it changes the language on the PiP window, and I have to use the language icon bar. Then, the PiP window becomes activated, and I have to toggle back to the window I was working on before (on which I wanted to change language). I have the "separate languages for separate windows" option activated.

It's been some months now, and all those things were working before an update but never came back...

Does anyone know if there's a way of fixing these issues? I've tried things I found online but nothing seems to work.

Many thanks

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?

I recently switched ISP and now when I try to google anything with firefox I keep getting this message appear:

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot."

It prompts me to click 'I am not a robot' then pick out which lights have cars etc in them. Worked fine before the ISP change. Some notes:

- This does not occur on Microsoft Edge or Chrome. - The only add on I have is Ublock but it still does this when I have that disabled. Plus I have Ublock on Edge and there are no issues.

If it's my IP address, then why does this ONLY appear when I use Firefox? Surely it would also appear when using google on any browser if my IP address was in question...

From what I am reading online, my only option is to either: - Use a different search engine ; or - Use a different browser.

I'm curious to hear other people's thoughts on this.

In the last couple of days I've been unable to login to my virginmedia accounts using firefox, all other browers work fine, I can enter details no trouble but as soon as I press the blue button on their page nothing happens, cleared cookies and data for virgin but didnt help.

Hi! Since updating Firefox to 98.0 I've been experiencing sudden performance drops(lags/freezes/stutters) while scrolling. `about:support` page shows that compositing is `WebRender`. The issue occurs with fresh profile without any addons installed and also in `firefox-nightly`(100.0a1). However, scrolling is totally smooth in 97.0.2 and earlier versions of Firefox.

What changes in Firefox 98 could cause this, and are there any settings in `about:config` I can try to tune to solve the issue? These are the settings I've always used, and, as I mentioned, scrolling was smooth before 98.0:

gfx.webrender.all = true general.smoothScroll.mouseWheel.durationMaxMS = 400 general.smoothScroll.mouseWheel.durationMinMS = 200 mousewheel.min_line_scroll_amount = 40 mousewheel.system_scroll_override.enabled = false

I have a locked file that shows up as Invalid Symlinks error. I am not sure but I think it may be Profile.ini Here is what I am getting that tells me its a Non-Existent Destination file. My question is why is it Invalid symlink and what can I do to fix it? Here is what I get: Lock In symlink folder /home/butch/.mozilla/firefox/6q1a4nt2.default-release 127.0.1.1:+2708 type of error Non-existent Destination File 2022-03-08 21:15:25

When I deleted it wouldn't open so I had to completely reinstall it. My Email address is: [removed email from public]

I continue to get message "Sorry, invalid login. Please verify the User ID and/or Password you entered." while trying to login to Altra Federal Credit Union. Never had the issue before on Firefox. I am able to login using other browsers. Altra has indicated to me an update glitch involving Firefox browser. Any help?

I'm using firefox 97 on mac. Whenever I copy and paste an image from firefox, the image comes out desaturated as if it is using the wrong color profile. I tried changing the gfx.color_management settings without it improving. The images look fine and are the right colors in the browser, however, the issue only happens when I copy and paste images. Firefox behaves like the color management is disabled (set to 0 in config) but ONLY when copying and pasting images.

I do not have this issue with other browsers such as chrome.

the web based software requires: "Firefox users must install the Microsoft .NET Framework Assistant add-on."

downloading / install: https://www.microsoft.com/en-US/download/details.aspx?id=42642

results in: .NET Framework 4.5.2 or a later update is already installed on this computer.

searching Firefox Browser ADD-ONS yields: 0 results found for "Microsoft .NET Framework 4.5.2"

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

I have two PDFs that I designed and uploaded to our website, but the headline in both displays with clipped characters in Firefox. Different fonts were used in both and the issue is the same. I even tried adding more tracking then re-uploading, the issue persists.

I checked in other browsers and the text displays as intended. The attached screenshots show the issue in Firefox, compared to how it should look (viewed in Chrome).

It's only this one line of text that is affected and I don't know why.

I don't like the new printer dialog box Firefox came up with. It is too basic. 9 times out of 10 I have to click over to the System Dialog Box. Is there any way I can permanently switch to System Dialog Box? I am running Windows 11/64

We are once again asking for Reading List on desktop

The data exists/syncs with our accounts, right? I don't want to use Pocket. Pocket...is lackluster at best. Why have Reading List at all?
