Can't add, change or save bookmarks in Mozilla Firefox - How to fix

https://mywindowissues.blogspot.com/2019/05/cant-add-change-or-save-bookmarks-how.html

Bookmarks and browsing history are stored in the Firefox profile folder in the file places.sqlite. If there is a problem with this file, your bookmark changes may be lost whenever you restart Firefox. You can force Firefox to create another places.sqlite file by deleting (or renaming) the existing one.

You might want to print these directions out, or copy them down to reference because you will have to close Firefox to delete or rename the files.

Warning: Once you delete the places.sqlite file, you will lose all of your browsing history. Firefox only keeps one copy of this file and there are no automatic backups for browsing history as there are for bookmarks.

1. Open your profile folder:
   Click the menu button  , click Help and select Troubleshooting Information. The Troubleshooting Information tab will open.
   
   • Under the Application Basics section, click on Open Folder. Your profile folder will open.
   Note: If you are unable to open or use Firefox, follow the instructions in Finding your profile without opening Firefox.
2. Close Firefox completely:
   Click the Firefox menu  , then click Exit.
3. In your profile folder, find the files places.sqlite and places.sqlite-journal(if it exists) and delete them (or rename for example, to places.sqliteOLD, to keep the old file as a backup) .

• (Optional) Also delete the file xulstore.json. This will reset any toolbar customizations you have made.

When you next start Firefox, it will create a new places.sqlite file and automatically import the most recent bookmark backup file. Your bookmarks will be restored from backup but you will lose your browsing history. Note that browsing history is used for the address bar autocomplete feature.

How to enable function keys without pressing Fn

http://mywindowissues.blogspot.com/2016/07/how-to-enable-function-keys-without.html

I own a G710 since yesterday and after installing Windows 7 everything works fine. But one thing is annoying me that I have to press FN to access the function keys (F1 to F12). Is there a way to invert this so you do not have to press the FN Key to access the function keys(F1 to F12) ?

Solution

Turn off the computer and turn it back on
Right after pressing the power button, start tapping F2 and you will reach the BIOS page
Go to "Configurations" tab and toggle the current "Hotkey" mode setting.
Press F10 once changed to save and exit the BIOS.

That should reverse the use of Fn.
