Diễn đàn hỗ trợ Firefox

I only want to block adverts when they are intrusive and I feel bad about blocking acceptable ads. Most ad blockers will allow you to whitelist a website but I often will not notice that the ads are being blocked and thus not white list it. What I want is an ad block extension to Firefox that only turns on for new sites when I tell it to, although it should be able to remember which sites I want it on for. I can't think of the best way to explain this which is why I couldn't find a solution on the web.

Does anyone know of an adblocker with this feature and how do I turn it on?

Hallo! The recent version of Firefox allows to open .pdf in Firefox. However, there is still allways the question how to proceed, even if I mark the box to make this unneccessary in the future. When I next time try to open a downloaded .pdf, the question is there again. (I hope you can understand the problem, I am not a native english speaker). See the attachments.

Best regards Fritz

Hi

Some months ago I added a 32" samsung usb screen to my PC, my operating system is windows 7, This maybe coincidental and not at fault. Since adding the screen my Firefox browser crashes, what happens is the screen starts flashing and most of the display disapears you can click on some buttons if displayed or you know where they are but the only way to stop it is to close and reopen the browser, it seems to happen more frequently in a browsing session once its happend once, sometimes it dosn't happen. It seems to be triggered by the mouse scrolling wheel. I have removed and reloaded Firefox but still the same, when reloading it recognises the previous instalation and recalls some previous settings, I don't seem to be able to stop this happening. Lastly the fault does not occur on any other browser. Firefox is my default and prefered browser and I would like to cure this if possible, I have run virus scans etc and dont appear to have any contamination issues.

Any advise gratefully recieved

Many thanks Steve Hull

After years of using Firefox for browsing, Yahoo has suddenly overwritten my Firefox blocking access and I cannot find a way of removing it on the Windows 10 software; as it doesn't show up as a separate app. Do I delete all Mozilla-Firefox programmes and reinstall Firefox?

Suddenly, all my passwords got deleted from Firefox last week, and when I went to check, I found that a new version of Firefox had just been installed on my windows 10 desktop. I got the passwords back, but not only do most of them still not work, but even when I sign in manually, they don't work, so I have to reset them for each site (and usually I can reset it to exactly the same password I have been using all along, which is strange by itself). The next time I go to that site, again my password doesn't work, so I open up Chrome and get in with no problem. Thus, it is not just the saving of my passwords that isn't working in Firefox, it is that these sites are not recognizing my correct passwords when I type them in manually on Firefox. Has this happened to anyone else had this problem, and is there a solution? I have used Firefox for years and love it, but I can't continue to use it if it takes me forever to get into all these websites. Thanks.

When I am trying to open site hypermission.ru in Mozilla I see some strange things. Big objects and broken fonts.

In other browsers I dont have the same problems.

Please, help!

P.S. I dont have some addons on mozilla. I use it clear.

I did not do anything and opening firer fox to get to my mail at inbox in outlook. I also use the calendar provided. Simply I can't get to my calendar it reads an err and try again later. Can you tell me how to get that back as I have a lot of data recorded on it? Thank you.

Up until the release of 78.0.1, I have been deleting items from the address bar by highlighting the item and then holding the Shift key and tapping Delete. This doesn't work now, much like when it changed from just hitting the Delete key, so what is the process for deleting specific items from the address bar now? The Help pages are no help because they still say to do the Shift+Delete way.

Speedtest.net is giving me different results than Vivaldi or Edge. The download testing speeds are all over the place and choppy compared to the other browsers, and a tad slower overall result too. The upload speeds are fine. What does this mean?

the browser does not want to allow me to open a page that its critical for me to monitor the position of my car through a GSM system that i have on it installed i got a message telling me the conection is not safe, and all that hapen after the browser got the last update

Whenever I type in what I want in my search bar and I press the "enter" key, it won't lead me to another site. (For example I type 'youtube.com' and it won't go to the website and will just keep me in the same tab.)

According to he description of “pinned tabs” (https://support.mozilla.org/en-US/kb/pinned-tabs-keep-favorite-websites-open):

   “Pinned Tabs are small, can't be closed accidentally and open automatically when you start Firefox.”

Unfortunately, this is no true. Often, I find that my pinned tabs end up moved to another window. I cannot say why it happens, but it certainly does, and often. I suspect it is related to dragging the mouse when I am trying to click. I am disabled, and sometimes my attempt to click results in some dragging. If you drag a pinned tab off the left edge of the window, it moves the pinned tab to a new window and unpins the tab. At this point, it is quite easy to accidentally close the tab, and the tab will no longer be automatically opened when Firefox is started.

It should not be so easy to drag a pinned tab to a new window. This behavior should be changed.
