Firefox Support Forum

I made a post the other week about issues I was having with Firefox & YouTube.

Having put the browser in safe mode I discovered that it was my ad blocker/s. That said, I had notice Firefox lagging or loading hard on video sites, not just YouTube as well as some applets on other sites. And having experimented with various ad blockers and video sites as well as my own blogs, I find that I am not having these problems with ad blockers in Chrome or Edge, but only Firefox, so much so, that most of these sites are entirely unusable unless I disable the ad blocker/s in Firefox.

Frankly, I've been noticing it for some time, but as of the other week they have nearly rendered the browser unusable, or the ad blocker/s unusable in Firefox on said sites. I have completely uninstalled and reinstalled the add-ons, from the Mozilla site, to no real avail.

It is not only annoying but very frustrating and I am about to give up, on the browser altogether. I am not having these problems with the same ad blocker/s in Chrome.

I've spent nearly two weeks on this and it hasn't gotten better.

There it is. Thank you.

I don't want the pdf to save to disk without my will when I open a pdf file from any website. Fire Fox saves the file first, then opens it for reading. How to change it? I want to read the pdf first and then decide what to do with it. This works similarly in Edge. FF is my main browser, I wouldn't want to change that, but I have too much garbage on my disk. every pdf is saved first, completely unnecessary.

I want to open online PDFs in Acrobat. I've modified the setting is in Firefox to "Always ask," yet when I click on a PDF it opens as it should AND Firefox automatically downloads the file to the Downloads folder even though that destination is greyed out in settings and the radial button for "Always Ask" is selected. How can I block this activity in either Firefox or in the registry.

NOTE: ALL OF THE SETTINGS IN FIREFOX SAY "ALWAYS ASK." This a software bug in Firefox, not a user switch setting. This activity began today (March 11, 2022) after months of normal, expected activity. I've reset Firefox and I've done a complete uninstall and clean install and this still happens.

Updating to version 98.0 onwards Firefox has started saving a copy of every pdf file I view (open) in my downloads folder.

My settings have not changed:

Tools->Settings->General->Applications: - pdf (application/download): Always ask - pdf (application/force-download): Always ask - pdf (application/pdf): Use Adobe Acrobat DC - pdf (application/x-download): Always ask

And when the "ask" dialog pops up, I choose "open".

I have tried all standard methods/troubleshooting, including resetting the handlers.json file.

The only way to avoid getting a copy in the downloads folder is if I choose "Open in Firefox" (application/pdf) instead of "Use Adobe Acrobat DC".

Any solution to this?

Thanks Michael

Before the new update whenever I downloaded a file it would ask where to save the file to every time, now it just asks once then automatically saves any new files I download to the same folder as the previous ones, forcing me to then go to that folder and manually move it to the correct folders. Is there any way to change it back to the right way it was done before they decided to remove our choice? My setting is set to "Always ask you where to save files", with the emphasis on "Always".

Before the most recent update (version 98.0), my default setting for pdf files is to open in Firefox and a pdf website I use prompted a download window when I clicked 'Download'. It has 'popupDownload=true' in the link which I believe did the trick.

After this update, clicking the same button just opens the pdf file instead of showing the download window, ignoring the command in the link.

Can anyone help me out? Thanks in advance.

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

I know Firefox recently changed some settings regarding automatic downloading of files, but I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? Thanks

For the past several months, I've had increasingly worse graphical errors on Google Drive. At first it was only in a few documents, and now it's in every single document. These errors only occur on Firefox, no other browser. Text that I type is constantly blurry, oddly-sized, or oddly-spaced, with some letters touching while others have large gaps between them. I've also had some other small issues, like the document thinking that I'm two people and asking me if I want to see "the changes made my collaborators" when I'm the one currently typing (the documents aren't shared with anyone else, and there are never any changes beyond the ones I make), or showing my cursor highlighted with my name as if I were someone else watching myself type. It's made it more difficult for me to focus on work and I don't know what to do about it.

I've tried the following methods (most of them multiple times over the past months) to solve it, none of which worked: - Running the windows in safe mode - Uninstalling all add-ons and themes, clearing cookies and cache, and then restarting my computer - Uninstalling Firefox entirely, restarting my computer, then reinstalling it - Refreshing Firefox - Looking through pages like Firefox Task Manager and such (although the information there didn't really mean much to me, nothing looked out of the ordinary)

Does anyone have any ideas about what I can do about this? I was ignoring it for a while since it's still legible, but it's become really annoying, especially when it makes some words hard to read. Thanks in advance for the consideration. Here's a screenshot of a document with the weirdly-spaced, blurry text:

My address line is red, and their is an icon which say: browser is under remote control, reason: DevTools.

I am not sure how to fix this, or what to do about this. I do not know if I caused this myself. Please let me know if anybody can help.

Firefox 98.0.1 will not load some web pages that other browsers will. I get a message about Network Protocol Error with the option to "Try Again" which hasn't worked. I've tried many of the fixes suggested here but nothing changes. If I copy the link Firefox won't open and paste it in Brave or Opera the link loads fine. I don't want to quit Firefox but I can't spend time every day trying to fix it either.

Hi there, I'm hoping someone can help with this. I recently signed into a shared computer with my personal Firefox account, and it automatically imported all my history, my browser extensions, and bookmarks, including personal/secure information that I wouldn't want on a shared computer. I tried signing out and deleting the sites and login information, even going so far as to completely delete all of my browsing history and cookies and signing in with another account, but all the supposedly deleted history and logins and extensions were then transferred to this second account. I have deleted all my data, even uninstalled and reinstalled Firefox, and all the data from my personal account keeps haunting me as suggestions when I type in the task bar or suggested usernames when I log in to websites. How can I actually delete this information so it's not on a shared computer? Thank you!

This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

Hi! Since updating Firefox to 98.0 I've been experiencing sudden performance drops(lags/freezes/stutters) while scrolling. `about:support` page shows that compositing is `WebRender`. The issue occurs with fresh profile without any addons installed and also in `firefox-nightly`(100.0a1). However, scrolling is totally smooth in 97.0.2 and earlier versions of Firefox.

What changes in Firefox 98 could cause this, and are there any settings in `about:config` I can try to tune to solve the issue? These are the settings I've always used, and, as I mentioned, scrolling was smooth before 98.0:

gfx.webrender.all = true general.smoothScroll.mouseWheel.durationMaxMS = 400 general.smoothScroll.mouseWheel.durationMinMS = 200 mousewheel.min_line_scroll_amount = 40 mousewheel.system_scroll_override.enabled = false

Hi , My main machine is a personal windows laptop. Firefox sync works fine and syncs all things including "all" my installed extensions . recently company issues me a macbook and on it when i install firefox and login my account for sync it syncs other things like bookmarks but does not sync all my extensions only a few of them.

I already tried multiple things like sync delibrately from windows and then pressing sync on mac or reinstalling firefox on mac . but its the same issue.

few of the extensions that are missing :

1. Auto Tab Discard
2. Download Manager (S3)
3. DownthemAll
4. Stylus ( very important for me)
5. Tab Session Manager (THE most important for me)
6. TamperMonkey ( Important)
7. (Temporary Containers)
8. uBlock Origin
9. Xkit Rewritten
10. Zoom Image

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.

This just started happening and I'm not sure why.

I access my email via a browser. When i compose an email If I have a .ZIP file that contains a bunch of files. If I want to attach say file # 6 and File # 7 to the email I am composing I would open windows explorer, traverse to the ZIP file location and click on it so it opens in windows Explorer. Then I'd highlight the one or two files I wanted and I'd drag them to the email.

This would typically attach the the files but it no long works - I have a feeling it may be due to windows 98 I hear you guys changed (fixed) how files are processed.

This is awful I now must extract those files to hard disk (of if there's another contained ZIP file within its even more extracting) - I'll this makes so much work and if I forget to delete all the files I execrated I'll run out of space.

Is there I setting that I can set to make it work the way it used to - I don't want to learn another browser but this change has killed my poductivity

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

Hello Community.

I've selected an option to open PDF's in Firefox for preview. And if I wanted to download the PDF after preview, I simply clicked the downloab button from the preview app/tab. The files were downloaded with default filename and to the downloads folder without prompts. But since a while ago the dialog where the save location must be selected and filename given for the file opens up after the click of the download button.

How can I change it back to the previous behaviour without having to input filename and select the file download directory?

I want to set a timeout for the master password. It's clearly a security threat to leave passwords unencrypted. It bothers me more than being prompted for the master password.

I remember we used to be able to set the timeout and it's a pain to go and logout the software security device after logging in to the one thing that needs the master password.
