Trying to access my Tesco account but a page saying 'Access Denied on this server' appears. Can you rectify this? I urgently need to login to my Tesco Account.

PS. I have tried to solve the problem for 2 days but no success!

I have a personal ' writing email' template in Yahoo mail which I use for a specific community. It contains relevant information which saves me from having to type it in everytime I email the community. However, of late when using 'Compose' the template appears but when I try typing below the salutation I cannot use the 'Enter' button to move the cursor down the page to create the body text. Consequently my emails are just one line of type with no paragraphing.

Why is this?

I deleted some emails on the weekend by mistake so I went into trash to retrieve them but couldn't find them. I checked again this morning and they are still not there. Please help Thank you, Basma Brown

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

I restarted my computer and when I booted Firefox up it looked completely different. I'm assuming they updated, but updates never impacted my settings before and in this case none of my sessions or history is left.

I logged in to my Mozilla account and that recovered my extensions, though not my toolbar settings.

The real issue is that all of my tabs and windows are gone. In History, "Recently closed windows" is greyed out and Recently closed tabs shows nothing but what's been opened since I restarted.

Is there any way to recover my history?

Edit:

Resolved: Somehow a blank profile had been set as the default.

Firefox crashed and I couldn't get it restarted. I had to uninstall it and reinstall it. I lost all of my bookmarks, logins and other information. What do I do to recover it?

I want to use a command option to open a new blank tab in a specified portable instance of Firefox using a specified profile.

I constructed my command like this:

"Path-to-Firefox-executable" -profile "Path-to-Profile" -new-tab "about:blank"

It partially works (it opens the correct instance of Firefox and uses the correct specified profile) however it always opens about:newtab instead of about:blank.

Seeing as I am specifying the exact page to open, any New Tab settings in the browser should not matter, and I should just get the page that has been specified in the command.

If I manually type about:blank into the url bar, then a blank page opens as expected, so the url is correct, it just won't work for me as part of the above command line.

Does anybody else have this issue? How can I get this to work correctly?

Recently reinstalled Firefox for Windows on a new PC, and have since been having issues with audio playing on only Twitter. I have tried reinstalling my sound drivers, clearing the browser history and cache, clearing Twitter's cache, reinstalling Firefox, disabling all my extensions and nothing has worked. Any help at all would be appreciated.

It is ONLY Twitter, and it works on all other browsers.
