Firefox Support Forum

can you help me to get this browser version installed on my mac as my customers are facing some issue which I wanted to test on this particular version only

pls help me here

After the last Firefox update, i am trying to open youtube.com in my Firefox browser but it's not letting me to do it. Every time i open it shows an error and says that the error is from YOUTUBE and FIREFOX or I can do nothing about it. But the funny part is its working on other browsers like chrome.

After I updated to version 120 when I open Firefox it immediately crashes. I've refreshed Firefox and opened it in troubleshoot mode. The error still occurs. I've fully deleted it and redownloaded it, still crashes. Sometimes it won't crash immediately and I can use it for a bit. I have disabled all plugins and deleted all extensions. I am still experiencing the crash. I have run an anti-virus check (Malwarebytes) and it didn't detect anything.

The page you are trying to view cannot be shown because an error in the network protocol was detected. Why do i keep getting this message only on firefox but all my other web browsers work fine when doing web searches

There are 2 processes involved in Firefox Sync, and 0 differentiation between them in the language used to describe what Firefox Sync does in any of the documentation, this makes nearly every discussion on the topic highly confusing to borderline misleading.

When you press Sync, you are pushing settings to Firefox servers. When you sign in to Sync, you are pulling settings from Firefox servers.

Both of these steps are referred to interchangeably as "syncing" and there is next to no documentation of what causes each to occur nor what they actually do.

Why is this dangerous you might ask? Well, let's say I buy a new computer, I want to set it up the same way I use all my devices, so I sign in to sync to synchronize my settings, makes perfect sense. Nothing tells me anything is happening when I sign in, so I click the sync button because I want to synchronize my settings with my other devices. Big mistake. I've just overwritten the server-side sync profile with a default Firefox profile. You know how you fix that? You sign in and press the sync button to overwrite the sync profile again. But you know what happens when you sign in? You become synced with the now blank sync profile and lose all the settings that you want to be pushing to the sync profile. This just happened to me. Thankfully I was only choosing to sync add-ons and options AT THE TIME and I have backups that are about 6 months old and I rarely change settings, but some things like my homepage URLs are something that I do change fairly often, and I'm sure some additional sites were whitelisted since by default I just reject all cookies. I also thankfully use policies.json to block updates so I didn't immediately get assaulted by that too.

SO! I HIGHLY suggest that when merely signing in to Sync, the default should be for syncing to be off to start off with, so that you can choose what to "sync" BEFORE it occurs. However, because of the language, the question arises, what am I choosing to sync for? Am I choosing what to PULL from servers? Or am I choosing what gets PUSHED to the servers? When syncing is turned on, does that mean I an pulling the settings that I have chosen? Or am I am pulling ALL settings while only pushing what I have chosen IF I click the Sync button? Or do I push EVERYTHING?

It's incredibly unclear how the Sync feature works and both of the "main" articles on it are completely useless for understanding it because the term "sync" is used interchangeably for pushing or pulling settings.

What are the correct steps to rectify this horrid situation? Sign-in, set-up sync, choose "Options" and "Add-Ons" again, THEN copy over the backup settings, THEN Sync them to the "cloud"? If I have 2 different devices setup with sync, and 1 chooses to sync options and the other chooses to sync bookmarks, then I click sync on BOTH devices repeatedly, what occurs?

It seems like more often lately that in the past. I just tried to post on the Portableapps website, and had all sorts of problems there.

I had to use Chrome to post. Actually, when I went first opened the page in Chrome, I got an alert that six trackers were found, and did i want to disable them.

Perhaps that relates to Firefox and accounts for some of the bad behavior?

I'm getting tired of this. There must be a happy medium between security and unencumbered usage.

Maybe it's one of my apps, i.e. Canvasblocker. It has a ton of settings options, and I don't have a clue what to do with them. Aside from that and Ublock, I don't see any others that fit that category.

Maybe it's something in my browser settings?

I try to install Firefox on a HP Z1 G8 desktop under Windows 11 Pro. The first time I get a warning that a .dll is not available or so (I dont know what this warning is precisely, becaus it pops up for 2 seconds only ) , and firefox is not well installed, reinstalling goes without warning, but still Firefox starts and then stay dead, no sites, no settings. I know the security in this computer is very thight, but other apps install without problem and functions.

Why Firefox cant be installed where other apps can ??????

who has experienced this also and has a clou ?? thanks Ferdinand

In the last few versions of Firefox the "Always ask you where to save files" does not work properly. Sometimes it asks, sometimes it automatically downloads. The majority of items I download are in PDF. Some I am asked & put on desktop to move later while some are automatically sent to Downloads folder. In Help, it says to go to Settings > General > Applications to get this to happen but under PDF I have it set to "Always ask". And Firefox is not doing this. Will this be fixed in future versions? There seem to be a lot of people that have this problem, which is basically creating work. I understand it only takes seconds to get them but over the course of time it's not efficient. I've been using Firefox for years & do not always agree with some of the changes but this one is really frustrating because it is not consistent. I only want to be able to have the where to/save as box show up when I attempt to download a PDF. Any other or real suggestions would be appreciated. Thank you, JF

2 step authentication does not get saved that i have to enter a code every time when i log in. it should have been secure for then next 30 days as the check box selected. it seems it's a big issue for so many users that i found no solution. this issue is so bad and it easily is one of the reasons they are skipping this browser.

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

I own a mac and had to erase all my data from my computer in order to upgrade to new system. Issue is - the apple support person did not remind me to save down my firefox browser data/bookmarks. Now my mac is updated and it's like a brand new computer. I searched previous forums and apparently firefox automatically saves down your data but I don't see it in the appropriate folder (Old Firefox Data >bookmarkbackups) - I see data from 2016 and 2017. Can I recover these bookmarks?? I had a lot of important ones saved..

Once again the failure of Firefox to work with comment sections of many websites has reared its head in the latest update of Firefox. I'm using Windows 11 with latest updates. This occurred suddenly in the middle of commenting. Other web browser are OK. These constant recurring problems with Firefox are getting tiresome and although I like the browser and am comfortable using it, I'm seriously considering abandoning it for these annoyances.

Hello, recently i installed Kubuntu 20.04 (KDE Plasma 5.18.8). I have this problem where firefox (version 100) is not rendering the window and i think it's the profile folder.

First i was thinking on the graphics. i have installed 'nvidia-driver-510'. I tried this Solution with no luck.

I have:

• Intel HD Graphics 620
• Nvidia MX130

I tried :

• Renaming the folder '.mozilla' to '.mozilla_bak' works perfectly but i have to do this every startup, and firefox creates a new profile where i have to logon in every platform i use.
• Downloading 'firefox-100.0.1.tar.bz2', it's the same, works fine with a new profile.

This lead me to the profile folder, running './firefox --profile ~/.mozilla/firefox/<profile_folder>' it's the same, not rendering the entire window. I dont know why my profile is causing this problem, i only use three addons: AdBlock, BetterTTV and FoxyProxy, i have the same problem even if i dont have these installed.

After i click on hyperlink and chose by default to open with Mozilla, nothing happen. I try in Options too, nothing I uninstall Chrome browser still same!!!

When there was chrome as option it will open with chrome, but i want to use only 1 browser

What happened to "recent bookmarks"??? I is no longer available....why???? I need it back, as I used it all the time and my bookmarks were very easy to locate. Now I have no idea where a bookmark is, that was even bookmarked an hour ago.
