Fórum da Comunidade de Firefox

Fairly frequently I need to send files I receive in .txt or .pdf format to my browser to read.

I have attached hereto two versions of the same file - one sent to Firefox and one sent to Chrome.

Note that the screenshot of the Firefox version of the file contains loads of UTF-8 character translations that are incorrect and show up as strange characters instead of letters or punctuation marks, while the same file shown in Chrome is almost perfectly clear.

I am running Firefox version 127.0.6533.89 (64bit) in a Win 10 Pro 64 bit environment that is up to date as of August 1st.

This has been a problem with Firefox for a very long time and I would like to know if I have misconfigured a setting that has caused this.

For about the past week I've been having trouble with Gmail and Google Search in my Firefox browser. Typically, I open a Firefox window with multiple tabs and leave the window open all day. I always have Gmail and Google Calendar open in tabs. What happens is that the Gmail tab will at some point give me a message that it cannot connect and has timed out and is trying to reload, but it never reloads, it just stalls. Then I try to open a Google search bookmark to search and the tab remains blank. This happens multiple times throughout the day. Meanwhile I can open Gmail or any Google page in Chrome, which I don't like using.

Sometimes I can close out the Gmail tab that won't load and try to open Gmail in a new tab, but that stalls out too. The only way I can open Gmail again is to close out the Firefox window completely and then relaunch it, then it can open Gmail or Google... until it breaks again.

This never used to happen. I'm using the latest versions of Windows 10 and Firefox on my desktop PC. Nothing else has changed.

Please help me fix this, it's very annoying.

Certain downloads will cause firefox to fail downloading then get stuck writing the file to disk and cause the OS(file explorer) to crash. While this is happening trying to close firefox will cause the os and firefox to crash. trying to open firefox settings will cause firefox to crash.Trying to restart wont do anything since the os(win10) seams to wait for writes to disk to finish before shutting down. I tried to download something overnight and woke up to this issue so it will never finish downloading/writing the file to disk. Only fix is to hard shutdown(hold power button) then delete the file and parts file before lauching firefox and cancelling the download imediately when it tries to download it again. While this is happening the disk its trying to write the file to will show 100% usage and 0 read and write speed. I doubt this is a firefox issue and probably something on my end but any workarounds or insight into how firefox writes files to disk will help me figure out whats wrong. sorry about the scuffed image but I cant save a screenshot while this is happening.

For 2 days now I have a big problem! Firefox froze, and I ended up closing it with the programme manager. When I wanted to reopen I got this: Firefox est déjà en cours d’exécution mais ne répond pas. L’ancien processus Firefox doit être arrêté pour pouvoir ouvrir une nouvelle fenêtre. BUT - it refuses to close when I click on "close" (fermer).

I tried the programme manager - but Firefox isn't shown as being open.

I've made a back up of my profile. I can't delete parent.block ... I'm told "Firefox is running already" and I must close it. Every troubleshooting step comes to the same barrier to completing it! Almost all guide one from an open Firefox page - and I can't open Firefox! I can't "uninstall" for the same reason!

All my passwords are in Firefox - and I can't import them to Chrome without closing Firefox completely! I'm going mad - urgent need to access my passwords!

Many web pages now 'flash' when opened in FF (128.0.3 64bit W10). ALL graphics images turn on then off in synchrony. Text does not seem to be affected. Disabling HW acceleration has no effect.

sample web page: https://www.cnbc.com/2024/08/01/eu-ai-act-goes-into-effect-heres-what-it-means-for-us-tech-firms.html This problem does NOT occur using Google Chrome. [One difference noted seems to be the TOP of the web page has an mp4 video advert. It displays in Chrome, but not in ffox]

I am using a windows 10x64bit desktop and I want to find a 32 bit version of Firefox for my laptop which uses Windows 7 x32bit. I have tried the download for customising, ie set it for Win7/8 but the version which is downloaded reflects on the laptop that that version can only be used on a Win 10 computer. Please give me a link where I can find the 32 bit version of Firefox meant for Win 7. THANK YOU.

Today I realized that I have installed two (2) versions of Mozilla Firefox on my Laptop PC which I rarely use.

Both editions are 64-bit type but one is version 109.0.1 (11/04/2023) in

C:\Program Files\Mozilla Firefox and the other is version 128.0.3 (28/07/2024) in C:\Program Files (x86)/Mozilla Firefox.

I suppose it is illegal to have two versions of the same App., so the question is how can I delete the old version (109.0.1) without affecting or damaging the new version (128.0.3)?

Thank you, JOHN HATZITOLIOS

I haven't loggued in to my matrix account in a long time. I didn't remember which way i used, so i used my email adress, which created a new account. Trying to log out and in again didn't showed me the other options such as login with mozilla (sso), so i deleted that new account (@sebbu2:mozilla.org). Meanwhile, I'm not sure i even am loggued out properly, since i get the same message when i try the original account (@sebbu:mozilla.org) that used mozilla sso.

Ever since the last update, I can't even use the home button anymore, as every time I click on it which I set as google's main search page, all it does is keep refreshing the current page I'm on, instead of redirecting to the page set on the home button, I have to rapidly click the home button around 30 times before it actually shows the google search page. I have tried everything short of completely reformatting the PC re-installing windows, and re-installing Firefox, I have even used Revouninstaller to completely remove Firefox and all files associated with it, and re-installed a clean version from the Mozilla site, dragged the home button to the tool bar, set the home button to google.com, and also set the opening page to google, then closed Firefox, waited around 30s, then started it up again, which did load up google's home page, then I went to youtube, played around there for a little while, then I clicked the home button, and yep, just as I suspected, it refresh the youtube page, I clicked it again, and yet again it refreshed the yourtube page, so I rapidly kept clicking the home button, until eventually the google home page appeared.

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.
