Diễn đàn hỗ trợ Firefox

I work with HTML website themes daily. I use the firefox browser for all of my design work and I have recently noticed that firefox does not show web icons such as font awesome or any other web icons. The web icons are properly coded into the theme and they show up fine in all other browsers (chrome, edge, explorer, safari).

I did some research on it and I did find this: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS but I don't know if that has anything at all to do with it or not.

If the problem is due to Cross-Origin Resource Sharing (CORS) then how would I fix that issue as the fonts are being served directly from the theme files?

Thank you

I'm a Firefox Developer Edition user. After upgrading my Firefox to 69.0b1, I see a problem about network and extension:

In the same network, the case when the browser stuck at loading the page content has been more frequent (especially on script-rich sites like Twitter). At that case, the extension menu is irresponsive (which means that when I click on it, it only shows a pop-up with nothing in it). Closing all loading tabs doesn't solve this. After a long time after the loading starts, the tabs suddenly continue to load and the extension pages come back responsive.

on one computer I have Firefox 68.0.1 32 bit and for Shockwave Flash there is an Always Enable option. on my main computer I have Firefox 96.0b.6 64 bit and I do NOT have that option. I have ASK to activate - which DOES NOT ASK and I have to enable FLASH every time I run a game on POGO.COM that uses FLASH. I have attempted to ask about this TWICE already and can't find my questions.

Website logon credentials are being reset after the use of the reload function - requiring the user to log back in to the comments section after each reload of the web page. In particular, credentials for DISCUS, which is very popular "comment" software used by many websites, is unable to maintain the users credentials after a reload...requiring the user to log back in each time. More info on this software is at https://disqus.com. NOTE: Addons have not changed since I was on 68.0.1 where this problem was not observed.

I have a normally used Windows 10 PC that I consider my standard configuration for Firefox. I WILL CALL IT PC A. I have another, rarely used PC which I WILL CALL B. The Firefox configuration on PC B is often not as up to date as PC A and may have old and outdated Add-ons, bookmarks, and tool bar configurations. When I bring up PC B and start Firefox, it will quickly start the syncing process (since I can no longer log off of Firefox - a very bad idea, by the way). Whether the sync starts immediately or not, how do I specify that PC B will always sync to PC A's profile and not try to update PC A with its old and invalid configuration?

For example if I go to https://jsfiddle.net/01tpr8sd/, a dialogue will pop up asking me which application I'd like to use to handle this link, while it should have triggered the internal U2F implementation. I have tried starting Firefox in safe mode and resetting values that look relevant in about:config but neither of them helped.

It doesn't happen if I create a fresh new profile though, but I really want to avoid the hassle of backing up all the extension configurations... Please help, thanks a lot.

I set up two Windows accounts on my Windows 10 and synced the passwords and settings in only one account. To my surprise, when I login in the second account, every login and password was there without the master password. This means that any one using that account can see my password.

I think this is a really serious security hole and Firefox should fix it as soon as possible.

running firefox dev ed rev 69.0b14

i run prestashop ecommerce on a hosting server. but when i use admin on my PC, i have an application that displays 2 sets of date/time, ie start and end.

however the 1st displayed time shows it correctly ie 26/08/2019 00:00 but the 2nd displayed time it is shown as 1566860340

the coding that generates this seems to be correct, check attached image.

any ideas please, as when I use any other browser it displays date and time correctly.

I opened Firefox this evening, and could not conduct any searches, and the search area jut read: go-tosearchitnow.global.ssl.fastly.net, and the page at the very top left showed "nothing here". It will not allow me to search. I just uploaded the latest version of Firefox, but still nothing happens regarding searches, and the same site and message still appeara

The latest Firefox update hide my bookmark toolbar and the menu bar. When I re-enable them, the setting is apparently not getting saved because they're hidden again the next time I launch the browser.

Windows 10 Pro Firefox 69.0

I just updated FF from 68 to 69 and now my menus are messed up. While preferences all set to English, top menu and context menu are all in Russian, addons too. Options are only thing that's in English as far as I can see. And it's not deletable from settings too (screenshot). Any way to fix it without reinstalling whole thing? (which is i'm not 100% will help but it's still last resort)

As per US-CERT "Mozilla has released security updates". but when I click on Help and About it shows Firefox is updated. Does this mean there is no need of update version I am using?

Any help will be appreciated. Thank you Ari

When I close firefox I have it set up to clear everything on the "clear history" list. Including cookies and cache. I use a program called ccleaner and it always finds tons of firefox cookies an cache.

In the Library window (show all bookmarks/history), pressing Delete deletes any highlighted item, but Shift+Delete grays the item out without deleting it.

What does this shortcut do?

I migrated to new SSD. I still have my old hard drive. I copied my previous firefox data from D:\...\AppData\Local\Mozilla\Firefox\Profiles to C:\...\AppData\Local\Mozilla\Firefox\ but nothing happened.

I also have a folder named "Old Firefox Data" when I re-installed Firefox, but nothing works. Firefox sync doesn't work either.

My About Profiles Page says I have 2 other profiles besides the one currently in use, when I launch them in new browser, I cannot see my old bookmarks and passwords.

I've also changed my mobile device, so I currently cannot access my old bookmarks and passwords. Even Lockwise.

As in the question. I'm having a problem with firefox, so decided to refresh it. But after 5 minutes it just reverts back to my old settings. All my old add ons reappear. Happened twice now.

I downloaded "AllFreeSoundRecorder.exe" and it downloaded fine until the last bit of download when the above error appeared and obviously I could not use the download. What can I do to fix this????

firefox updated and so did my windows 10 pro laptop. Tried to log in to monitor which was on the opening page of the browser when it popped up and now I get forbidden 403 code. What changed and why? what do I do?

running Firefox browser 69.0 64bit on Windows Server 2012R2 0) http://rockbridgehunt.org/ 1) click left menu tab "Foxhunting" 2) click left menu tab "Autumn Fixture Card pdf" blank page console log shows error: "uncaught exception: 2147746132" What does this mean?

Both Chrome and IE browsers display the proper page "http://rockbridgehunt.org/archive/2019/19FallFixture.pdf" without error.
