Mozilla, the firm behind the popular Firefox web browser, has released a guide to spotting potential online interference ahead of the European Parliament elections.
The guide includes tools to identify bot accounts on social media, as well as information on the EU, fact-checking resources and tips on how to spot misinformation online.
European elections are due to take place on May 23.
Social media giants Facebook and Twitter have announced their own programmes to target and prevent potential election interference via their platforms.
Mozilla said its EU Elections Toolkit had been created to explain the mechanisms of the internet - including bots and targeted advertising - in "easy-to-understand language" that would help users make "independent, informed decisions".
"Online manipulation of voter views is a growing problem and many of those voters are essentially defenceless against absorbing disinformation and misleading ideas disguised as 'facts'," the company said.
The toolkit also includes guidance for people on how they can improve privacy settings on their accounts and for their web browsing habits.
Mozilla's Firefox is the world's third most popular web browser, behind only Google's Chrome and Apple's Safari.
Voters will choose 73 MEPs in 12 multi-member regional constituencies.
Each region has a different number of MEPs based on its population.
Eight MEPs will be elected to represent the north west.
MEPs are elected by proportional representation, in order as listed by their party. The number of MEPs each party gets is calculated using a formula called d'Hondt, except in Northern Ireland, where the Single Transferable Vote (STV) system is used.
European Union citizens living in the north west are eligible to vote in either the UK or in their country of origin but not both.
To vote in the UK, they must be registered to vote and have completed an additional form available at www.northwestvotes.gov.uk
The deadline for the return of this form is also Tuesday 7 May.
