My PC crashed and when I try to open firefox I get this error

XML Parsing Error: undefined entity Location: chrome://browser/content/browser.xhtml Line Number 732, Column 15:

I saw this answer https://support.mozilla.org/en-US/questions/1303747 but I don't understand anything from it, English is not my first language. Will I lose my bookmarks and extensions? Do I delete the folders in program files or run the uninstaller? When running the installer there is an option to "restore default settings, remove extensions etc", should it be on or off?
I deleted the folder, ran the installer again and set the option to restore default settings off, and still can't open firefox. Can someone explain in simple terms?

Hey there ! i am working in hospital as Approval Coordinator using https://onlineservices.bupa.com.sa. Before sometimes Firefox was working 100% correctly, but after update , i cannot able to print the document correctly. scale feature is not scaling document , moreover please include some ruler option under print preview screen, so that we can adjust the print. i have been using Firefox for more than 15 years.

I've already found the solution, but wanted to share that Version 90 created a problem with Print Preview and Shrink to Fit. Uninstalling Version 90 and re-installing Version 89 fixed the problem. With Version 90 the Print Preview function (which I love) didn't work properly. When I try to Shrink to Fit any page, the first page shrinks, but the second page isn't pulled into the first page. Also, there's missing information on both pages. If there's another solution so I can use Version 90, please tell me. If not, and Mozilla is doing away with Print Preview (and Shrink to Fit), I'll have to do away with Mozilla Firefox. Sorry, but that's the main reason I use Firefox over Chrome. Perhaps I can find another browser to do what I want. I hope not though.

First of all excuse my English because it's not perfect. The problem came with the new version 90.0.1. There are some websites I visit every day, and after installing new version of FF I noticed that the fonts used in websites are different than it was before. Some websites are breaking apart and doesn't look like they did before, and like they look in other major browsers right now.

Examples: http://www.alterego.co.rs/_knjigovodstvo/aktuelno.html https://www.arrowheadpride.com/

I went to the Settings option and saw that my FF is set to show Times New Roman 16 as default font, but if I go to Advanced I can see that the checkbox on Allow pages to choose their own fonts, instead of your selections above option is ON. So websites should be shown not by default font, but the font used in websites. But if I turn that option OFF, than I can see websites like it should be, like it was before new version, and like it's shown in other major browsers. But it gives me wrong look (font) with some other websites, so it's not the permanent solution. I guess it's some kind of problem with new version of FF.

Note: Same thing happend a couple of weeks or months ago with one of previous FF versions, but that was fixed just day or two later with another new version. It looks like we have simmilar problem right now.

Thanx in advance for any help, and I hope somebody will fix that soon. I am lifelong user of FF browser because it's my favourite and the best, but that kind of problem can be pretty big for someone who is very often online and who is working in developing websites sometimes.

Thanx again Dragan

При загрузке сайта DNS-shop.ru сайт не догружается (загружается только базовая информация о товарах без картинок) и все, процессор уходит в нагрузку 100% и нагревается до 75 градусов. С Edge таких проблем нет, сайт грузится быстро, не грузит систему. Браузер самый свежий, AMD Ryzen 5950x, остальное думаю не важно.

Firefox ESR 78.11.0 version. For some reason lately a few users have been experiencing crashing of firefox. I'm tried going forward to 78.12.0 and backwards to 68.9 and it still keeps crashing. What could be some other fixes besides refreshing and running in safe mode. It still crashes performing both methods. Thank you!

1. When I have to move another windows across FF, I get a string of repeating images one of the other that I cannot remove until I close that FF page. (See image below)

2. When I save a FF page, it does not close itself. I have to click on the page, refresh it, then I can close it. Also sometimes it take 20-30 seconds to save and close a page that has mostly text on it, such as an article page from one of the many newspapers I review every day including Financial Times, NYTimes, Wash. Post, etc. Due to this and other errors, it slows down my work day to where I am forced to spend one to two extra hours workiing to correct these errors.

3. When I have FF open, it seems to slow down my entire machine, even though I'm not working at the moment in FF.  

4. Please fix this. I work 7-8 hours a day on a project I am nearing 20 years completing. It gets tiresome in and of itself, but when FF causes me more problems it become exasperating and as much as I want to quit, I can't walk away from this project which has grown to nearly 700 gigabytes in size with millions of pages of html, jpg, pdf and txt files.

5. Please help me with a new update that will fix these errors or tell me how I can fix them.

Thank you.

Is it possible to lock Firefox extensions? By locking i mean make the extension inaccessible (prevent disabling it or changing it's settings but having it still work).

https://github.com/mozilla/policy-templates/blob/master/README.md#extensions

Does this "lock" mean what i just described?

{

 "policies": {
   "Extensions": {
     "Locked":  ["jid1-p8wT8wUxc4KaJo@jetpack"]
   }
 }

}

That is in my policies.json file, is this how it's supposed to work since it does nothing for me? I'm not sure if the id is correct, could someone tell me how to find the right one and if this is right, then what's wrong? Thanks in advance.

I am constantly frustrated by unresponsive pages / script warnings etc using Firefox. This never used to happen on previous builds -- I am using the latest 86.0 -- but these occur so often that I am about to say goodbye to Firefox. This does not happen when I am using Chrome and other browsers.

I have been through all of the suggested steps to deal with these unresponsive script/page issues, and none has worked.

Would appreciate any help on this, but as I say I am about to leave Firefox at this point for Chrome and other browsers.

Thanks in advance...

Hi,

I know this is been asked and discussed multiple times over the years. But the current [CTRL+TAB] and [CTRL+PGUP/PGDOWN] are less that optimum for people who use Mac's.

We like to use CMD+[CTRL/SHIFT]+Left/Right. If there would a menu item for the two operations then it's quite easily do do via keyboard settings. But as that has been removed we're stuck with something which doesn't really work on notebook as there aren't any PGUP/PGDOWN keys ....

Please make it programmable or add the "Next Tab..." and "Previous Tab..." back to the Window menu.

Cheers.

Trying to use a virtual terminal for my credit card processing for my business but firefox is not giving access to share location to the site even after I have manually allowed location sharing. This is the message I receive when I try to use the terminal: Sorry, we can’t load Virtual Terminal. We couldn't access your location. To use Virtual Terminal, allow Clover dashboard to know your location on your browser, then refresh the page How do I get this corrected?

Hi,

I just installed Clean My Mac, and clean junk files. After that, I open my Firefox, and found a problem with Facebook Business Manager font.

The font displayed on that site is not normal.

1. I've checked my other Firefox on other device, they are run normal. 2. And when I turn troubleshoot mode to on, the font was normal too. 3. My other Firefox profile on other device run normal.

I have uninstall Firefox and delete leftover file, and then reinstall it again. But same condition.

Maybe there are issue with Firefox or my device (because I delete the junk files that may be needed by Firefox)

so, what should I do?

Additional Info: - MacBook Air - MacOS BigSur 11.4

Thank you

I hope I can fix these, don't wanna stay on 88.0.1 for a long time :(
