I quitly searched Help for 'default browser' for Firefox. And suprise they had Seamonkey instructions to make it as Default Browser; From the Dock, open Safari. From the menu bar, click the Safari menu and select Preferences.... Click the General icon, to display the General preferences panel. In the Default Web Browser: drop-down list, select the browser you want to make default. Quit Safari. Also in firefox Options/Advanced/General(tab) is a check box to make or not make firefox the default browser.

the PC Optimiser Pro is malware and has to be treated as such so using a remover program that will actually take on the job and do a full removal including the hundreds of entries this nasty puts into your registry is essential, using the regular uninstaller will not do the trick. You need to be rid of this thing and it is likely where a lot of your problems are coming from. You have a malware infection. If you want help to run some scans and see what else may be happening in addition to that being installed then I would suggest heading to LandzDown and posting your own thread in this linked area Analysis and Malware Removal you will need to register first, if you need any help let me know I am there also. I think it would be a very good idea seeing the issues are having to go ahead and let the team at LZD help you run some scans to see just what all has installed and what has been affected. This is my best suggestion to you. You will be helped step by step to clean it from your pc. If you want to try using revo and hope it clears it fully here is that link Download Revo Uninstaller Freeware When was the last time you ran a fully updated malwarebytes scan on this pc?

Never mind.....I went to Firefox troubleshooting, and I think it's fixed. If not, I'll be back. For some reason, it wasn't selecting the right printer name. I had to select it manually, then it was okay. I don't know why this would happen, as every place else was selecting the one I have marked as the default printer. Shirley

i made a few that i was trying to create sort of a universal one...where all you have to do is change the picture, basically plug in your own image. those are the last ones i did called "backgrounds" and also another one with the morning glories. it might be a bit intimidating, but if you install them, go to add ons (in your browser), click edit...it brings up the code. if you scroll down to where theres a web address, and erase that one then put your own pictures web address in, it will show that image in the background. and with the text box defined with a different color, so its not just on top of the image. if you felt bold, you might even take that one (the daffodils) and then go look for where the text box color is, figure out the number of the color you want....and then change that number to whatever color you want. you can also use them on top of each other. the simple font and color changing one that molanic made will help a lot with the colors of links, size of fonts, and such. so you can start with which ever one you like best, then install the color changing one to add the text boxes, the font size...etc...and it will be both at once, and work together. yeah that would be the easier way to get the daffodil one to have more variation. this is the one that changes colors and fonts: https://userstyles.org/styles/110474/gardenweb-houzz-colors
