Diễn đàn hỗ trợ Firefox

Around July 2nd I opened FireFox to find that the text on whatever screen I was on is spaced in an ineligible form. It seems to be the correct spelling, just jumbled together. I've tried adjusting the fonts, browser acceleration, to no avail. It's becoming difficult to read, and it has only been affecting the desktop browser. It works just fine on my Mac and phone, but not my windows computer. It is the only application that does this. I've updated my drivers and all.

The "Post" button is off screen on the share popup when I try to share a post in a Facebook group to another group. The problem has been getting worse. Usually I can see a slim piece of the top of the button, but today it disappeared completely. The only way to make it visible is to press Ctrl -. Then select Zoom > Actual size from the menu when I'm finished.

Firefox restores a window session from before the last time I closed the browser every time I start the browser.

At one point after reinstalling firefox I had two windows open with tabs in each. I closed the one window first with a couple worthless tabs in it before using the other tab that I'd used to continue browsing and continuing my various tab groups. Ever since then, EVERY TIME I launch firefox it launches that other window with its tabs first, although allows me to "restore previous session" overwriting all but the base tab. How the hell do I get it to fucking stop doing this? I just want the last window I closed to be the "previous session" but every single damn time it launches this unwanted window and tabs as the default! I've tried countless times to close the entire browser with the window I want but it still reverts to the previous window!

I have Mozilla VPN installed on my computer, but not in Firefox. Recently, whenever I turn the VPN on or off, the tab I have open in Firefox reloads. This usually doesn't matter, but sometimes it's really annoying, like when I'm really deep in an infinite scroll website. I want to turn it off, but I tried turning accessibility.blockautorefresh on in about:config, and it still does it. I don't want to blindly mess with settings when I don't know what they do. Does anyone know if there's a setting/group of settings I can use to stop Firefox from reloading on network change?

I believe when I wanted to update to a newer Firefox version, I chose the one right before the change to tab history where it said something about not saving as many presumably due to websites that can open several pages within a tab in a second or 2.

I don't know if this is the cause, but now whenever I open several YouTube pages it can fail to save one of them to web history. I don't know if it's because some pages open a &pp= page first and then when it switches to a clean video ID URL Firefox doesn't log all of them because of that tab history change?

Either way I'd also like to revert that tab history change if it's not the cause, is there already an about:config setting? Or is this just like the tags-in-history-window change and it will never be re-introduced..

I'd probably need to update Firefox within a few years anyway when some new thing unsupported on older Firefox is introduced, so if I revert to v131 that works better I may be in the same position a few years later. Idk if I can revert with the current profile data anyway.

In the past couple of weeks I've noticed this happening a lot; particularly in YouTube. Menus don't show items (regardless of appearance color mode) until I refresh the pages, or thumbnail images fail to load. Sometimes the images will load after waiting for several minutes. Drop down menus won't sure their items unless I refresh the page.

I tried Microsoft Edge and the problem doesn't exist there. I prefer Firefox, but don't like these annoying glitches.

I've also noticed, again on YouTube, if I'm watching a Playlist, the comments under the video are not shown IF I have the playlist open on the side, but if I close the playlist or change the video mode to Cinema Mode, the comments suddenly reappear.

Again, this issue doesn't occur if I use the Edge browser.

I've ruled out my BitDefender Internet Security App and its VPN.

Thanks in advance for any help.

I have horizontal tabs in Firefox 152.0.4 on a Macbook with Tahoe 26.5.1. My tabs have suddenly reversed order, so that the most recent ones are at the left and the older ones towards the right. Strangely, if I open a new tab it appears to the right of the current tab. I tried closing Firefox and reopening, but it did not change anything. Is there a way to restore usual order of tabs so that the newer ones are at the right?

When I start my computer I want my "startup" tabs to open in the order I want; [app.Inbox.com, AOL.com, mail.google.com (xxx00xxx@gmail.com), mail.google.com (xxxxxx00@gmail.com)]. ALSO ‘sometimes’ at startup TWO tabs for app.Inbox.com appear and I don't want that.

This morning I was signed out of my VPN and it didn't even open when I logged into my PC. I was getting targeted ads when I opened my browser so was confused. Opened the VPN, was logged out and search around the internet, unprotected, to try and gain access again.

Now, what is the point in a VPN if I have to rummage around the internet all the time first in order to hide my presence. Why? was I automatically logged out? Why were the settings on my computer changed such that the VPN was no longer enabled as a start-up app? How often will I be logged out of my account in the future? Why does Mozilla of all companies still think I am logging in from a different location every time when I access my account even without the use of their VPN?

I'll be able to get some peace of mind if these questions are answered and I'll be able to change my provider if not.

Thanks, Dan

Firefox unable restore session when switching profiles and instead opening apps installed on the profile I'm switching to.

I have installed Whatsapp web (web.whatsapp.com) on "Profile 1" as a Windows app.

I have some tabs open in "Profile 1" and I switch to "Profile 2" and close the "Profile 1" window with "X" button of Windows 11 but keep the Whatsapp window open.

When I open the "Profile 1" from profile menu, my expectation is that, those previous tabs should be restored, but firefox is opening the Whatsapp web app/window.

When I add sites for exceptions, why isn't this carried with my Firefox account and it shows up in every instance of Firefox when i am signed in? It is a nuisance to keep re-adding them everywhere. Also, when Firefox updates, why do I have to re=enter what I already done. It is a pain.

When using a tab inside a collapsed tab group, if "open link in new tab" option is used, the tab group expands unprompted. As a result I have to keep collapsing the tab group again and again and again, slowing down the browsing experience. Is there a fix for it?

Why doesn´t the new checklist widget (that apperas on a new tab) sync between my different computers?? As it is now, it is totaly useless. If i create a checklist on my homecomputer (logged in with my firefox account) it does not show up on my work computer (also logged in with my firefix account). Eveveything else is syncing fine, but not the widgets...

Issues with redirect. A group I am a member of uses Constant Contact. An email is sent with a link to a report. Receive this error:

Server Not Found

Firefox can’t connect to the server at deuaxb4ab.cc.rs6.net. What can you do about it?

This worked last week.

Firefox 152.0.4. Win10

For quite some while now, when I pull up my site history, it doesn't matter what I search, the search returns no matches found.

Yesterday, I visited a site. Today, I pulled up the history (^H) and then proceed to search for a word I knew was in the title of the page because I had printed it and had it in front of me. It was not found. I then searched manually through my history and found the page.

See attached screenshots.

1. Searching for the word "corn" and not being found in the history
2. Manual search shows the content exists with the word "corn"
