Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

For about two months, video quality has been persistently low for me on Youtube. Quality options are limited to 360p and I am unable to change it. Additionally, I am unable to play video on other platforms such as Vimeo, Pinterest and other streaming sites. Sites return errors such as 'Player is unable to play video at this time' or error code 102630. I have refreshed my cache and reinstalled Firefox and neither have resolved the issue. Notably, this issue does not occur on other browsers such as Chrome or Microsoft Edge. As far as I know my drivers are up to date and the Windows Media Feature Pack is installed, although it shouldn't be an issue seeing as sites work on other browsers. The issue also persists in troubleshooting mode. I've gone through the console and included images of some interesting errors that might be of use, although I don't have the technical knowledge to know what they mean. Please inform me if there is any other information I can provide that would help. Thank you!

I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

I use Firefox web browser, my OS is Windows 10 pro. I am the webmaster for site http://eckankarinoklahoma.org. When I revise and update the website pages, Firefox does not recognize the changes made until I hit the reload (renewal) button to the right of the address. However, when there is no reload button for a page, Firefox never will recognize the changes that have been made until I delete my browsing history. It appears to be read web history pages. I've tried everything, from reloading the page to getting out of the site and returning, etc. to get Firefox to recognize the changes but it will not. Like I said, the only way I can get it to recognize the changes is to delete my history, which is a real pain. The page that doesn't have a reload button is a password protected page. See site mentioned above and click left hand menu item "Members Login here." However, by visiting this page you won't be able to see the problem until you have visited it, and then again after it has been revised. The only revision made to this page is the date in the label asking for the password. The password works fine, it's just that the label never updates and this is important for users to know in which article to find the password. Sorry for the wordiness of this, but I hope you get the idea of the problem.

After Firefox updated my browser version to 129.0, my username and password no longer work on my credit card website. I contacted tech support at the credit card banking site through a live phone call. I told them about the upgrade and also that I can use Firefox on my iPhone to login successfully. I don't know what version is currently on my iPhone but it does work there. This problem is specifically on my Mac Mini. I also can login using same password and username on the Mac through Safari. Their tech support said the problem is with that version (129.0) Firefox web browser. What say you? Thanks.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

When I receive an email that has a link, Firefox opens without any of my settings. This also happens with Firefox pop-ups, which indicate I don't have certain products, such as Web Advisor, even though I do.

I guess the first question is why a new iteration of Firefox is opened when I already have it running.

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

How do I get the + sign back on my tabs? After latest update I can only close tabs instead of opening new tab, and I am talking about after opening several tabs. When I have seven tab open, I have to do ctrl+t to open new tab instead of just clicking on the + sign that use to be at end of tabs. Yes, I do use custom settings. This happened before but I was able to fix by going to tabs under about:config, but it seems the setting is no longer there.

Since 128.0 was installed outlook.office.com/mail has stopped working. (Windows 11)

My mail account has numerous shared groups. However these now fail to load with a messgae "Cannot load folders for "xxxxxxxxx" Decoding failed.

Additionally, while I can see new mails in the list (under focused and Other), the previews are all blank.

I do not get this error in Edge or Chrome in Windows.

Hi,

Firefox Developer Edition 126.0b7 (64-bit) shows a perpetual "Loading" screen when trying to access my internal Logitec Media Server at 127.0.0.1:9001.

Other browsers like Waterfox Classic have no trouble, so LMS is working fine.

I tried cleaning the cookies, disabling the firewall (Windows 10), that did not help/

Any idea how to solve this?

Thanks.

Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.

This is my second email to you....

I just switched to Firefox from Chrome, because Chrome was crashing all the time.

All I want to do is sync my computer, laptop, phone and Ipad's reading list. I want to be able to see an article on one device, add to the reading list, and have it on all devices.

I'm logged in under the same name on all, and it says sync is on, but the reading lists are different.

Can someone help me? My phone number is [removed phone# from public support forum], email is [removed email from public].

Thank you!

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠️ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button   

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

   Settings -> Privacy & Security

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

NOPE - lost all my bookmarks, extensions, settings - not going there again thank you

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

Hello, Since the version 128 (x86_64) on Windows 11, SSH links are no more opened with the user. The link tooltip at the bottom of the screen is showing the link without the user too. Ex: ssh://root@10.0.1.1 -> will open ssh://10.0.1.1 instead. Thank you in advance

Regular download works fine, but when I try to download attachment in outlook.live.com website, it didn't ask me where to store it, but simply places it in my default location, while at the same time opening the attachment even though I only want to download the file.
