I have defined custom fonts for some languages, but they're not appearing as I defined them. Instead, the OS default fonts are showing up.

This is happening after I reinstalled Firefox in my device. Before that, the fonts were appearing as defined.

For example: English text is using Arial instead of Noto Sans, and Japanese text is using Meiryo instead of Noto Sans CJK JP.

For the Japanese font, it does show up correctly in the address bar, but not in the page itself.

After a windows update yesterday, when I started Firefox it didn't load my previous session as usual. Previously, I've been able to go to settings and restore the session, but there were no options for that and the relevant session wasn't shown in the recently closed tabs or windows, even though the history was intact. It loaded a new/blank window, and since then when I close and either re-open or try to restore a previous session, it only opens the tabs that I've opened today.

Firefox 118.0.2 (64-bit), Windows 10 PC.

Here are the steps I've taken:

1. Turned off the "Open previous windows and tabs" in the startup options to get access to the "restore previous session" option
2. Gone to the profile folder and copied, then removed the contents of the sessionstore-backups folder
3. Copied the relevant backup session file (looks like it has the tabs I need when I scan it) to my desktop and renamed it "sessionstore.jsonlz4"
4. Replaced the existing "sessionstore.jsonlz4" file in the root profile folder with the new one from my backups
5. Reopened Firefox

It still just loaded my tabs from today, and doesn't show the session I'm looking for in recently closed tabs or recently closed windows. When I go to about::sessionstore, it says it's having trouble getting my tabs and pages back, and there's no option to reload a session.

I checked my sessionCheckpoints file in my profile root folder, and it only had these values: {"profile-after-change":true,"final-ui-startup":true,"sessionstore-windows-restored":true}

I updated it to include these values and restarted again, but the result was identical: {"profile-after-change":true,"final-ui-startup":true,"sessionstore-windows-restored":true,"quit-application-granted":true,"quit-application":true,"sessionstore-final-state-write-complete":true,"profile-change-net-teardown":true,"profile-change-teardown":true,"profile-before-change":true}

When I open the sessionstore.jsonlz4 file in Notepad++ I can read it normally, and when I just double-click to open it in Firefox it appears to parse correctly in terms of both structure and data... the tab 0/entry 0/URL shows the URL of the first tab that I had open, tab 1/entry 0/URL shows the URL of the second tab, and so on. So it looks like the data is there, but I can't seem to force Firefox to load that.

Any suggestions for what I'm missing?

I'm running Windows 11 and the latest version of Firefox. In settings, we are presented with two options when opening a new tab: customizable Firefox home page (with a Google search field) or blank page. Neither is acceptable. I want my default home page to appear when opening a new tab. How do I achieve that? Why is this simple option apparently not available?

Hi, I seem to have an issue with Firefox rendering pages with artifacts. I use Linux Mint 21.2 Cinnamon, video adapter is Intel HD 4000. Currently running 6.2 kernel, tried to fall back to 5.15 which didn't change anything. Attached the examples, the first 2 are screenshots of the about:support page, the issue appear there consistently but not necessarily at the same place. I've tried to open Firefox in the Troubleshooting mode, and the artifact appeared right in the dialog asking for restart! (see pic. 3) Enabling software WebRender (gfx.webrender.software=true) fixes the issue.

I have tested memory with memtest86+ overnight with no errors, CPU has been tested by Prime95 for 3-4 hours, the iGPU seems to be working fine either in Unigine Heaven, GpuTest and glmark tests. Is there a way to fix the issue other than disabling HW compositing?

I have an email account blocked (jgcaller129@gmail.com) and have tried the sync tab at the top corner of my computer. It sends a message with a number to this blocked email to unblock it- how am I supposed to get an email from you on a blocked account. How do I unblock this account. I have tried several times with the same result now the icon to sync isn't there anymore. PLEASE HELP This email is very important to me. You can send a reply to an alternate email account (also linked to Firefox -jgcaller15@gmail.com).

I use Firefox on two different Windows machines, my Android phone, and my Android tablet. I am signed in to the same sync account on all of them. I would like to be able to see the history from other devices, or preferably, a chronological list of sites that I have visited in a single list.

I'm currently using Firefox on my home PC and when I click on the "Firefox Account" button, I can see a list of tabs that are open on the various devices. But when I go into History/ManageHistory, I mostly see the history of just this PC. I see some items from other devices, but a very small percentage.

Windows 11 updated to latest version, Firefox 118.0.2 64bit version.... My issue is when I view a website and try too highlight words the copy option isn't available, its there when I right click but it kind a faded out, Is there a setting I need to change or whatever? Thanks

Hi, Description: Sometimes when I move my cursour over certain elements on a website, black or white Blocks appear. These Blocks are always rectangular but usually not sqare. Oftentimes the block will have Diagonal lines running up to the top left corner of the Box. The apperance seems to be connected to mouse movement. They pop up and dissapear only when the mouse is moved. And stay when they have appeard and the mouse isn't moved. Esspecially highliting things makes them occur. Example images are provided. Occurance: They are not limited to one website, though they don't seem to appear everywhere. Their occurace seems to be consistent. They are not limited to websites however. White boxes can also appear over highlighted text in the URL, regardless of the website. Example image is attatched The Boxes occur in no other Browser and in no other Programm. They have been there for a while, so it's not the version. Tried Fixes: I uninstalled and reinstalled Firefox. The boxes also appear in Private windows. I used the suggested feature for removing all settings and addons. Interestingly if I run firefox in Troubleshooting mode none of the Boxes appear.

Like I said, I only have these issues in the Firefox browser, so if it is a problem with my system itself I'd love to get your Ideas to what might cause them.

Pubmed Central (https://www.ncbi.nlm.nih.gov/pmc/) is a commonly used website for literature reading in life sicences research. I found that it takes a lot of time to load the PMC web page, and even worse to access an aricle in it, always more than 10 seconds (for example, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1234567/). These pages access smoothly in other browsers on my computer (MacBook Pro with M1, macOS Sonoma 14.0). I've tried the troubleshoot mode, and clearing all the cookies and cache, but it just doesn't work.

Hoping to get some useful feedback on this!

I have the same issue as this guy https://support.mozilla.org/en-US/questions/1402931#question-reply Exceptions. I have a new Dell pc and my Mozilla browser is 118. I have had this issue from the time that I purchased the new pc and attached it to my old Dell monitor. I've had Dell and Geek Squad involved both before and after I found this guy's fix in the Mozilla faq's. Before finding that I have had the new pc checked, the old and new monitor checked. All turned out fine system wise. So first suggestion from Dell - new cord - HDMI to VGA - didn't help. New monitor. Didn't help. Finally after much purchasing of technology and no changes a Dell tech was on using Edge browser. I realized that the monitor was perfect and told them so. So they tried Chrome and still the monitor text was fine. Firefox - back to blotchy. That's when I did the search in Mozilla faq's and found this other issue and "fix". I talked a Geek Squad tech into changing my display setting to "Extend Display" in Windows. Text totally disappeared from the monitor. So I've run out of options other than to set up everything under Chrome or Edge which I really don't want to do. But I may have to. In the meantime I've proved that I didn't need a new monitor or a new cord.

The image below is a camera picture of text on the monitor.

Help!!!

I had to reset my PC without being able to back it up first. I found the saved bookmark jsonlz4 files in the Windows.old folder and tried using Import and Backup in the bookmarks manager, but the bookmarks wont load. I tried https://www.jeffersonscher.com/ffu/bookbackreader.html to convert the file to json but that wouldn't load either. I even tried converting the file to HTML and import that way without success. It gives me the notification that restoring will replace all my current bookmarks, but nothing happens after that.

I'm at a loss as to what to do. How can I restore my bookmarks? I'm on Windows 10.

When I highlight text and move my cursor down to the bottom edge of the screen to scroll, it is super slow when going down. However if I do the same and scroll upwards by moving my mouse cursor to the top edge to scroll, it scrolls at a reasonable fast rate. The issue does not fix when I start in safe mode, or in private windows. The issue is exclusive to highlighting text and holding down to scroll. My scroll speed by clicking the scroll bar is normal, and so is using two fingers on my laptop (Asus Zenbook 14) to scroll down.

I don't encounter slow click and drag scrolling on google chrome.

I just downloaded the new Firefox and replaced the old application. All my bookmarks are gone. When I go to Manage and Restore, it tells me to choose a file but I don't seem to have the file on my computer. Under library>application support there is no Firefox folder. There is a Mozilla folder, but the only thing in it is the "extensions" folder with one file. I have a backup of my full computer on a hard drive from before the download, but I can't seem to find a file there either. I don't think I ever specifically asked my computer to save the Bookmarks. Does it auto save in the application? Is there a way to restore the prior version of Firefox on my computer?

On upgrading to Firefox ver 118.02, I cannot get any toolbar icons to appear in their correct place on the bookmarks toolbar. Instead they are crammed in the middle of the second (address) line. The double chevrons can be used to access the remaining of the toolbar icons.

Dragging a link to the toolbar space is not allowed.

Please fix this. I need easy access to ALL my toolbar icons, and have an expanded search box on the second line.

I am often now getting messages that Secure Connection Failed though I can connect to these sites through other browsers. It is getting annoying enough that I am thinking of switching away from FireFox as my default browser if there is not a simple fix. Thanks, Claire

I use 118.0.2 (64-bit) because I do not like the newer versions, but every time I open it I have to decline two consecutive Firefox popups urging me to upgrade to the newest version. Since I open Firefox dozens of times a day, these constant popups are driving me crazy. How can I stop them? Thanks.

Used firefox for many years on all my computers using OS 7 and 10 but today when I clicked on firefox I got news feeds . I have been trying all day to remove them , I might also add that all others computers with my account on has also got the same news feeds on .

How do I remove them I even tried to restore my windows 10 desk top today to a early date but now that computer wont even boot up .

Will someone please tell me how to remover the news feeds .

Many Thanks

How do I stop getting this translation pop-up Firefox puts on my screen? I do not want this service, and I do not want Firefox to be putting ANY pop-ups on my screen, to include to tell me there's a new version available. Firefox has become the pop-up problem.
